Yes. The cars were designed with that sort of future compatibility in mind. That is how they were able to implement and demonstrate the battery pack swapping station. While I personally don't believe there will ever be as many battery swap stations as there are super chargers, it is quite believable that in 5 to 10 years I'd be able to drive somewhere and swap out my aging battery pack for a new one that will have a higher capacity than what my original pack had when new.
