IME, if the chipset and CPU are Intel, it doesn't matter how new or old, booting
will be possible even with a minimal module set in the initrd. Xorg may or may
not work without a newer kernel or driver version, but it won't prevent booting.
Ethernet may or may not work, but simple reconfiguration for the different MAC
address usually fixes that. I have nothing using Wireless, so can't speak to
that. I've done this Intel to Intel type of transplant many times.

Putting a disk from an Intel system into a system with AMD, VIA or GeForce
chipset is almost certain to fail unless the initrd includes most drivers. This
leads me to believe that a minimal module set initrd created on one chipset type
and tried on any other chipset type is mostly likely doomed. However, when the
disk can be prepared in advance to ensure most modules are included in the
initrd, then the transplant should boot regardless, and only network and Xorg
and/or Wayland might need manual reconfiguration.
