Yes, provided you don't insist that a session bean is one-to-one with a usecase.
Sometimes you may choose to have one session bean handle several use cases, eg
order entry and order modification; at the furthest extreme you may choose to
have a single Session Bean to handle everything that users with a certain role
(or set of roles) need to do, so that a Stateful session bean instance in effect
represents a logged-in user. This is an attractively simple design for a small
application.
