One solution may be to test if there are nodes for the termX and after 
display it. (This code is writing without test and only via memory)
<?
if (db_result(db_query("select nid from node where tid = %d limit 
0,1",{here the tid of termX})) == 1) {
    echo "termX of vocabolary Y";
}
?>

Ok, the code is not well performant, but it is a start.
