I'm not experienced with thinkpad but I do have some laptops and desktop and in all of those suspension and hibernation works, require swap but even with zfs raid over luks layer with zil on pcie mounted optane on old ubuntu 18.04 things worked.. but i agree that on some hardware linux sometimes need patience :( hope that will change.. but probably to change linux need more love from desktop users ..
