In general, this is good to consider, but it is not the cause for this 
problem.
Calling a script with a missing interpreter gives a different message 
that comes from the shell:

$ cat /tmp/test.sh
#!/bin/xxx
$ /tmp/test.sh
-sh: /tmp/test.sh: not found

In this case it was possible to call "busybox", but "busybox reboot" 
gave the same message, so it must come from the reboot applet itself, 
therefor reboot is executed.

I get this message if /sbin/telinit is missing:

execve("/sbin/telinit", ["/sbin/telinit", "6"], [/* 65 vars */]) = -1 
ENOENT (No such file or directory)
brk(0)                                  = 0x63c000
brk(0x65d000)                           = 0x65d000
write(2, "reboot: No such file or directory\n", 34) = 34
exit_group(1)                           = ?
