Ok if it is a Vm what kind of finger pointing could be there? I think about performance and special setups. Virtualization is expected to abstract hw. If the vm image format is convertible I don't see why hypervisor/hw should matter.
As first I could thick about performances, then guest agents not being available in vendor image, third strange network configs hard to be attained without kvm.
For sure centos+your hw (can you buy the same machine?) should be near 100% ok!
Other combinations should be checked for previous 3 points and if they are ok don't see any issue -

An obvious question is... does the customer have any needs beyond this that might influence it?
Wait is it to be run for your business or for a customers of yours? If it was for internal usage my previous post still hold. Otherwise I think that keeping the default witha 3rd party is better. Can they understand where a real issue is in case of finger pointing?

Beyond the aforementioned finger pointing, what prevents you from running the VM on your current virtual infrastructure w/o purchasing an additional server?

just the hypervisor I think

Current infrastructure or not is a separate discussion point, and not one I need to have here. I know what is where with current infrastructure and how much that will weigh into a decision.
This discussion is strictly regarding the information provided in the OP and follow up clarification posts.

It sounds like the hardware will just be running one VM. Built-in back up on Hyper-V Server 2016 all the way via the host, no issues there if you can use block-level storage for your backups. It's so much easier and faster to backup and restore the VM as a whole anyways... no VM agent needed. Also, you get the option of "production" checkpoints (snapshots) on 2016. That's definitely noteworthy.
What specific features are you talking about here? I have Hyper-V 2016 server up in a lab environment but have yet to actually test anything.
I mentioned two in there. Windows Server Backup, and "Production Checkpoints".
I was not sure if those were that actual names of the features. I will have to check into them.
Obviously Windows Server Backup used to be a specific thing in full installs of Windows Server. Likewise, Checkpoints are a standard thing, but I have not heard about Production checkpoints.

https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/user-guide/checkpoints
Windows 10 and Server 2016 Hyper-V
Standard Checkpoints -- takes a snapshot of the virtual machine and virtual machine memory state at the time the checkpoint is initiated. A snapshot is not a full backup and can cause data consistency issues with systems that replicate data between different nodes such as Active Directory.Production Checkpoints -- uses Volume Shadow Copy Service or File System Freeze on a Linux virtual machine to create a data-consistent backup of the virtual machine. No snapshot of the virtual machine memory state is taken.

This is fairly low cost. Go with the vendor for the extra 20%. 2k isn't much. Should you save that now, and lose 'all' support, its only a few days of work on one issue, unsupported, perhaps less if you have to hire additional help, and that 2k is spent.
One place to point the fingers at - spend the 2k.
I'd make sure to have the support contract read and understood in detail to make sure that 2k actually gives me good support though.

always using these in my hyper-v

Thanks for your comments all.
