Yes, if he installed a variant of the OS that contains a backdoor in the
TCB. (This is true regardless whether we have constructors or not.)
This is one thing the TPM is supposed to make harder, on the premise
that the user can check what variant of the OS exactly is installed. Too
bad it is not really feasible in an overwhelming majority of situations
in practice.
