in most cases, no
i don't know how well the empty net stats are kept, but i usually go with pp to decide what are the chances someone scores with the empty net.
i generally consider SO a 50/50 proposition most nights so unless there's a reason i think they have a better shot than that to score with the extra man, i wouldn't count on it. and for the most part pp% for any team on a good night is around 25%.
but if team a looked real good in their last pp and you're sick of watching that game, then sure.
