It seems to me that the Raspberry Foundation chose the Broadcom SOC of the Pi because it used the Videocore VI (Pi 4/400) or Videocore VII (Pi 5) which is documented and for which there is an Open Source driver. .
Well my last info on that is it still goes down to a binary blob, but even if it was 100% opensource it would still a different architecture compared to the Radeons so surely some extra work.
Also since we don't have PCI(e) slot everything would either be supported onboard or via USB dongles. All to get inferior single core performance (thats all that matters for now) even when compared to dumpster dived AMD CPU from 2010 (not suggesting that those would or should be supported).
All these ARM vs AMD discussions tend to boil down to "it might not be worse" with some sprinkling of "I think it would be kinda cool, just can't tell you why".
Now if we think far far ahead to ARM or AMD laptops you run into the same problems for general IO, power management and touchpads with the slight difference that integrated GPUs on ARM will not be the same as on the rPI and most likely not fully documented while on AMD you might get to the point where the lowest iGPU shares it's architecture with some discrete Radeon already supported.
