Yes, since the bootloader is responsible for booting you into that 
single user mode ... they typically have a way of preventing that ... 
but as you have shown ... with physical access and a knoppix disk it 
doesn't matter how the OS on the machine is configured.

Physical security is the first assumption of any computer security I 
should think.
