Yes, it is possible.  There is something called "Bombay blood group,"
first seen in (but not limited to) India.  Bombay blood group person
appears to be Type O by conventional blood typing, but is actually
lacking a precursor from which the A and B antigens are formed.  This
person may still carry A and or B antigens, which can be passed on to
offspring, and since offspring will most likely get the functional
precursor from the other parent, the combined outcome can be a type A or 
type O child.  (Two Bombays could produce a Type AB child but this is a 
quite remote possibility, since Bombay blood group is "rare."
