F-2 nonimmigrants are a subclass of F nonimmigrants, so they are indeed eligible for automatic revalidation because they are included in the statement about "F and J nonimmigrants." Of course, the other conditions also must be met. For an F-2 nonimmigrant, the I-20 of the principal F-1 student from whom the F-2 derives his or her status must be valid, and the F-1 student must not have violated status otherwise.
