Not absolutely, no.  I just tried it:

$ ln -s /bin/bash aaa
$ ./aaa bbb
./aaa: bbb: No such file or directory

It announced that I tried to run aaa, and it couldn't find bbb.

$ rm aaa
$ ln -s ../busybox aaa
$ ./aaa bbb
bbb: applet not found

That implied I tried to run bbb, which I didn't.

Dangerous, I don't know about, but it's wrong.
