That's nowhere near as true as it once was. Most of your big well-supoorted distros run flawlessly on most big brand machines.

Where you'll run into problems is in using more obscure distros that require a lot of tweaking and customization, but something like Ubuntu should run beautifully out of the box and if it does have a problem it will be very well-known and heavily documented with easy to follow step by step instructions on fixing it. Linux just isn't the pain in the ass it used to be. Or at least it doesn't have to be.

Big brands like Lenovo, Dell, Intel work with Ubuntu pretty fine, there are compatibility tests for distros. I blind installed openSuse (after running Ubuntu beside W11) on my Lenovo Yoga from 2020 without issue aside from fingerprint scanner. All my NUCs have been great on Linux.
