He could, if he knows the *exact* offset from the beginning of the 
BOOTP/DHCP packet of the field in question.
That assumes, of course, that it *has* an exact offset.  The offset of a 
given option depends on what options are in the packet before the option 
you're checking, so it might be different in different packets.
