That's because IBM-PC compatibles (machines by non-IBM manufacturers that had a BIOS compatible with IBM-PC software) couldn't use "IBM" in their marketing, so they just called themselves "PC-compatible", or later just PCs to distinguish them from machines using other architectures, like Commodore's C64 and Amiga or Apple's Macintosh or Atari's home computers, among others. Eventually, the Mac and the IBM PC line were the last two standing.

Didn't apple's move to Intel make them PC compatible?
It that's the case then Apple stopped being PCs with the move to ARM.
