I would imagine that reloading the router would have accomplished the
same effect as re-issuing the config command, but I have not had a
chance to test it.

IOS does warn that after you submit this command:

    system mtu jumbo 9000

that a reload is required for it to take effect, but no such warning is
issued for this command:

    system mtu routing 9000

Because of that first requirement, we do reload the box after applying
the config template to it, so I think I can answer "yes" to the
question.
