I have a keyboard problem with a Lenovo Thinkpad which won't boot
because it detects a stuck key. The error code implies that the
offending key is the numeric 6 key but it's not physically stuck, I've
prised off the keycap and the rubber dome underneath moves freely with
an audible click so I'm assuming it's a short circuit problem inside the keyboard.
I might be able to source a replacement keyboard but I'd like to check
that there's no other problems with the laptop before doing that. I'm contemplating disconnecting the ribbon cables for the keyboard and
plugging in an external USB keyboard for testing. Would this be likely
to work and if not is there any danger that powering up the laptop
without its internal keyboard could be harmful?

99.9% sure that you can power up without the keyboard; and Thinkpads
are about the best laptops to disassemble & remove the keyboard (unless
it's a pretty modern one; I have a T14s with a keyboard problem which
looks like a pain in that regard)
What you suggest is exactly what I would try.
