All my x86 laptops have worked fine. It's only ARM because the hardware is extremely proprietary.
I mean, if it isn't a supported platform that's hardly the operating systems fault. However there are plenty of systems that do have drivers and are supported.
The original quote was that the best supported is WSL, and that is not true.
However, I recently bought myself a Windows laptop (for games and miscellaneous other things). When I've tried doing a bit of development on it I've been pleasantly surprised. The WSL2 integration works well enough that it actually is probably easier than my development environment on MacOS where I have to worry about lots of subtle differences (and since getting it replaced with an M1 MBP due to the battery expanding - some not so subtle differences).
