The MaxxFan Deluxe Roof Vent # MA00-07500K that you referenced just needs a 12V power source so it certainly could be wired to your van's battery instead of a separate auxiliary unit. The potential risk with this application is draining the vehicle's battery which could leave you stranded. This is why powered accessories like this are generally wired to a separate battery that can simply be charged from the tow vehicle or with a charger like the CTEK # CTEK56353 to maintain a steady source.

The MaxxFan draws 5 amps of power during operation.

Hi. If I use my van battery, and if I replace the standard it came with (2020 Ford Transit 250), could I have a bigger battery put in, reducing the risk of running it down?

You could potentially have a bigger battery put in but I would definitely check with Ford directly just to make sure there aren't any restrictions or precautions you would need to adhere to on the Transit. Even with a bigger battery you will still need to be mindful of how long you're running the fan (without the vehicle started).
