On my X1 Carbon 10th Gen, I can confirm my 'sleep state' in UEFI/BIOS is set to "Linux" - as per lenovo's instructions, and I use Xorg exlsuively - via Ubuntu Mate.
I can confirm that this mitigates the problem, but still occurs occasionally.

On my X1 Carbon I seem to have solved the issue by:
1. changing the BIOS so the Sleep State is in mode "Linux" as opposed to "Windows and Linux"
2. using Xorg instead of Wayland. -> When you log in, before inserting the password, click on the cog on the bottom right and choose the "Ubuntu on Xorg" option.
YMMV, but since I lost a day I wrote my solution here in case it helps
someone.
Bug description:
I've installed Ubuntu 22.04 on the ThinkPad E480. Suspend functions ok
intermittently. Some times it works fine, other times the computer
does not enter the suspend mode (the screen gets blank, but the
machine is still running and the ThinPad led is on, and there is no
way out... no response from keyboard or mouse... the only solution is
to switch off manually hitting and holding the power button), other
times the machine does not wakes up from suspension mode.
