If Linux decided to switch to a different license, like say a BSD-style that would allow Apple to do the things they want to do commercially, then Apple might consider that option. However, the probability that Linux will switch to a license that is sufficiently Apple-friendly is precisely as likely as Apple switching the core of their OS over to Linux. In other words, approximately 0.00000000000000000000000000000000000%.
