They’re all basically PCs so you can actually still install Linux on them

Not even all PC’s play nicely with Linux, especially in smaller form-factors and laptops etc. I’ve had several laptops with weird hardware that didn’t have a proper driver (esp tabletized devices with odd audio, video, or network chipset revisions). My last laptop I had to run a bunch of hacked-up scripts to get the audio working (amp would sleep and not wait) properly until kernel support improved about a year later

Linux is versatile, but one shouldn’t automatically assume it’ll work on Linux.
