No. The length can't be longer than the variable.
It is documented under SYMDEF for IEASYMxx in the MVS Initialization
and Tuning Reference. The first sentence documents it, but I've included
the entire text from the fine manual.
"The length of the resolved substitution text cannot exceed the length of
&symbol, including the ampersand on &symbol and excluding the
single quotation marks on 'sub-text'. For example, although the length
of sub-text exceeds the length of the symbol &FRANKIE in the
following example, the symbols contained in sub-text resolve to
1268ABC, which is a valid substitution text:
SYMDEF(&MARYJOE.='1234568')
SYMDEF(&FRANKIE.='&MARYJOE(1:2).&MARYJOE(-2:2).ABC')
However, the definition &JOHN='JOHNDOE' is not valid because the
resolved substitution text JOHNDOE contains more characters than
the system symbol &JOHN.
