I’m not sure exactly what you are asking. I think the Lenovo ThinkPad folks have done a great job of being real community citizens and putting in their own work.
Lenovo is a big company, though, with a lot of different areas and a lot of different concerns. The teams responsible for this device aren’t necessarily closely connected with the people on the ThinkPad team doing Fedora stuff.
In a lot of cases, hardware will indeed work fine, but hasn’t been officially vetted — Lenovo isn’t going to put promises on that.
