No, but here is head of main from ppmmerge.c:

int
main( argc, argv )
    int argc;
    char* argv[];
    {
    register char* cp;

again:
    if ( ( cp = rindex( argv[0], '/' ) ) != (char*) 0 )
	++cp;
    else
	cp = argv[0];
    if ( strcmp( cp, "ppmmerge" ) == 0 )
	{
	++argv;
	--argc;
	if(!*argv)	{
		fprintf(stderr, "Usage: ppmmerge ppm_program_name [args ...]\n");
		exit(1);
		}
	goto again;
	}

#define TRY(s,m) { if ( strcmp( cp, s ) == 0 ) exit( m( argc, argv ) ); }

    TRY("bmptoppm", bmptoppm_main);
    TRY("gouldtoppm", gouldtoppm_main);
    TRY("ilbmtoppm", ilbmtoppm_main);
    ...

No, I have done

and it works, but this method consumes 9MB instead of 1.5MB of disk space.
