Yes, but to use such a method you have to be already logged into the machine
with DOS or another non-OS.
If you only allow Linux to run on the machine, I guess a non-root user
is not able to poke around in the BIOS (correct me, if I'm wrong).
But, of course, you can use a screwdriver and take the harddisk with all
the data with you. To prevent against this one can use a cryptographic
filesystem. But then you can ...
And so on ... There is no absolute security.
