Because you cant reach the jumper / battery on a thinkpad because you
are unable to access the motherboard.

That's true. I have cleared many BIOS passwords by clearing CMOS. But I

Uhm most mainboards nowadays have a jumper called CCMOS or Clear CMOS
this
will totally erase the passwords and reset the BIOS to default settings
