Only by a hugely complicated and wasteful set of hardware hacks. 
Concealed ROMs, special boot procedures, hypervisors, etc.  If you can't
control the hardware, then you can kiss any chance of securing the
system goodbye.  If anyone can put that CD in another running computer
and start reverse engineering it, then it effectively has no security.

That's why I come to the conclusion that giving them no reason to 'break
in' in the first place makes more sense.

Have fun,
