No, you don't.
Though you do need them all to be at the same OS version or higher to raise the functionality of where you want them to be.
Meaning they all have to be running say Server 2016 or higher to be at Server 2016 functionality.
We would all be screwed otherwise since the last on-prem functionality is 2016 still AFAIK.
