Yes, you can. If you're going to freeze it, we recommend assembling the tart, freezing it, then baking from frozen. Put the assembled tart on a baking sheet lined with parchment paper and carefully freeze it until the tart is solid. Then, wrap it well or store it in an airtight container for up to 3 months. Unwrap and bake from frozen, adding 10-20 minutes of cooking time.
