No. You can have new version busybox, for example as /bin/busybox-new.
with more applets or without any apllets.

Example two (non busybox host):

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

Absolutely equivalent ;-)
