The post is really only an anecdote about a ThinkPad, and a relatively old one at that, which is probably as good as it gets in terms of Linux compatibility.
I personally more or less agree with the title, though, assuming a suitable hardware choice. I have a new-ish Ryzen ThinkPad for work and the only issue I've had is Gnome occasionally semi-hanging, and I don't know if that's just because of Ubuntu being a bit flimsy or because of something more general such as an issue with the AMD graphics driver.
Also, the Teams client the post mentions is about to be dropped by MS and it was never really that good to begin with, but having seen about two decades of desktop Linux, I'd rather be surprised that it's been available and worked somewhat reliably at all without hit-and-miss with Wine.
