Nope, because the dom0 provides a nice hardware abstraction layer. 
Basically, as long as they're compatible architectures (ie you can have an
x86 and an amd64 box, as long as everything's running 32-bit userland) you
shouldn't have a problem -- so long as you're running dom0s that are
appropriate for the hardware, the domUs on top don't care.
