I just replaced my T410 with a T480, and have been very pleased so far. Installed Debian on it without a hitch. I got a model with the dGPU, and it's working fine so far—I only use the dGPU when I'm gaming on Windows. I might be losing some battery from not properly disabling the dGPU when running under Linux, but I haven't bothered to check yet (battery life has been good enough). The machine is very very fast. One caveat on the T480: only the versions with the dGPU have two heat pipes—the iGPU models have one; therefore, apparently the dGPU model has better cooling, regardless of whether you're using the dGPU or not. The T480s has two heat pipes regardless of whether you have the dGPU or not. The /r/thinkpad subreddit has a lot of conversations around the thermal engineering of each model—lots of information to consume there. I greatly prefer my T480 to my work-issued Macbook Pro Retina—more ports (Ethernet!), more flexibility (I can configure it to not automatically go to sleep when I close the lid), and a vastly better keyboard. It's also easier to service and more upgradable. I was able to get seven+ years out of my T410, and I intend to do the same with my T480 (at least that's what I told my wife, to justify the cost... :-D ).
