If Intel can manage competitive technology node, it's not any more difficult than moving for new TSMC node.
Every time there is new possess, high-end micrarchitectures are redesigned and optimized for the new process.
Apple isn't going to keep x86 around just for them. But if Intel could actually produce Apple's M- and A-series chips, it might be worthwhile to increase supplier diversity, even if the ramp-up was painful...
