Yes, same thing for wifi, but with one extra complication.
If you're using wifi, by default you'll get a new local IP address for your laptop every time your wifi reconnects, and you'd have to change the port forwarding to match it each time.
You should be able to get around this by setting up your laptop to always request a fixed IP address when it connects, or setting up your router to always give the same IP address to that laptop. (search google for "DHCP fixed IP" along with your laptop or router model)
