Of course. The normal indentation for cpp directive is column 0:

int main ()
{
    if (x)
        {
#ifdef DEBUG
            printf("null");
#endif
        }
}


Normally, cpp takes into account only directive whose '#' is in column 0.
That's why you sometimes see directives indented this way:

#ifdef COND1
#  ifdef COND2
#     ifdef COND3
#     else
#     endif
#  endif
#else
#  ifdef COND2
#  endif
#endif
