A factorial design can be either: Full (all possible interactions) or, Fractional (without all interactions, but some). Therefore, a "factorial design" does not necessarily implies it is "fully crossed". In the OP's case, where: two factors A and B are crossed, if every level of A can occur in every level of B. It will be a full factorial design.
