    The C standard says (ISO/IEC 9899:1999, §6.10.3, 2):

    An identifier currently defined as an object-like macro shall not be redefined by another
    #define preprocessing directive unless the second definition is an object-like macro
    definition and the two replacement lists are identical. Likewise, an identifier currently
    defined as a function-like macro shall not be redefined by another #define
    preprocessing directive unless the second definition is a function-like macro definition
    that has the same number and spelling of parameters, and the two replacement lists are
    identical.

    So the answer is no.
