Tidy way : -

You can do that from LSM (Linux security module).

Untidy way : -
Yes, you can do that by registering a new binary format handler. Whenever
exec is called, a list of registered binary format handlers is scanned, in
the same way you can hook the load_binary & load_library function pointers
of the already registered binary format handlers.
