Apple already made it possible on macOS to run x86_64 software on their ARM computers, with Rosetta 2. Any company with enough resources could do the same if they felt so inclined. And if Apple wanted to, Apple could make Rosetta 2 run on iOS devices. For now they want to keep them mostly separate, and are more about running iPad apps on macOS than the other way around. But there is nothing stopping Apple from running desktop software, whether compiled for x86_64 or for ARM, on iOS devices if they wanted to. And if convergence turns out to be the future then I think we may see them do that eventually. But I am not convinced that it will.
