I second the Thinkpad. I've been using a X1 Carbon w/ Archlinux and it's great, almost everything works straight out of the box - and the archwiki for Lenovo products is quite comprehensive (https://wiki.archlinux.org/index.php/Category:Lenovo https://wiki.archlinux.org/index.php/Category:Lenovo). The one thing to be wary off is some alterations they made to the keyboard/trackpad in a few of the models (I think they may have reversed the changes most recently, but make sure you are getting the classic one).
