Apple has done it before though in recent memory.
People who don't know Apple would at least consider this claim....
1) A major advantage of Apple is vertical intergration.
2) Apple has invested hundreds of millions into acquiring ARM talent.
3) OSX and iOS are becoming more alike.
4) ARM performance is still rapidly increasing.
5) iMac and Apple servers have not recieved much focus and making up less of their revenue.
6) "Good enough" computing was achieved years ago (even Intel admits that Core 2 Duo years ago basically meets this bar.)
7) Battery life and size have become more important than performance (see Intel's recent and upcoming architectures)
It's not hard to consider that ARM may be appearing in at least the MBA in a few years.

ARM doesn't have to be as fast as x86. ARM CPUs only have to be good enough.

Intel is fast approaching the mW power scale with x86 while still maintaining the performance levels expected of this legacy ISA.
On the integrated graphics side of the equation, I see Intel winning by a long shot again as mobile graphics are still three years away from where consoles were seven
years ago which is ~ 250Gflops in raw compute compared to the fastest mobile graphics of 75Gflops.
I just don't see Apple moving away from Intel in their Mac lineup as it will mean Bootcamp and thus Windows, will be unable to work on Macs.
The vertical integration may be reason for Apple to go with ARM. They can differentiate themselves better than using commodity x86 parts. Look at the iPhone 5's A6... it's a customized of Cortex-A9 with huge memory bandwidth and perfectly fits their needs.
Don't forget Windows supports ARM now...
