Yes you can. It is about an hour and 15 each way, but you need to get off of the ship, get the rental, navigate the congestion of Cannes, navigate the congestion of Aix and then get back in time to be onboard by all aboard, no later than 5. You will have a couple of hours in Aix one of my favorite towns (first stop on the honeymoon what can I say).
While you can - I think the stress would not be worth it. Aix is a city of leisure a place for long lunches and evening strolls, and petanque in the park- it is the anti stress. If you go be sure to have trip insurance and remember that trip insurance will not cover if the adjuster feels you did not leave enough time to make it even if your problem is a breakdown or accident.
