Linux has supported a lot of CPU architectures pretty much from childhood but never had any legacy to carry over. Legacy is the real killer when talking about such migrations and the bigger the footprint with consumers, the bigger the legacy. Linux never had a significant footprint in any long existing segment at the time they migrated from one architecture to another, especially not in a consumer one. Take Apple and their move from 68K to PPC to x86 to ARM.
