I know nothing about non-Thinkpad Lenovos and but with a quick googling I wouldn't put my money in one. As far as I'm concerned they might as well be Acer laptops.

When people say that Lenovo laptops work well with linux they mostly mean Thinkpad series and even then there are some exceptions. Best out-of-box experience will be with one that has intel cpu+intel wireless+intel gpu and was released a year ago. It's about as safe bet for a high quality fully working linux laptop as you can get.
