It isn't in the SQL standard, and it would have undefined behavior: the 
sort order of a result set without ORDER BY is unspecified, so you would 
have no way to predict which rows DELETE would remove.

You could use a subquery to achieve this:

DELETE FROM table WHERE x IN
    (SELECT x FROM table ... ORDER BY ... LIMIT ...);
