Worth pointing out that while linux has usually worked quite well on thinkpads, official support for linux was very infrequent until recently. Also, support for linux on non-thinkpad lenovos was much more of a crapshoot. For corporate linux support, Dell (edit: and HP!) has always been a better option.
Edit: And apparently even today is very limited. Just checked Lenovo's website, and apparently only two models can be ordered in the US with linux preinstalled: X1 Carbon, and the Yoga. That's it.
Even for framework, the official Linux support isn't much better. They don't ship with Linux and it's only recently all the kinks have been mostly ironed out with the distro they recommend, Ubuntu 21.04. They have been making proactive steps with Linux support, like providing prerelease hardware to maintainers of lots of distros, but they don't officially support any distro.
