I don't know for sure but I would think that they could. Even though it is QS at lunch and you don't have a dedicated server, there are CMs in the dining room to help you if you need something. My daughter wanted some mayo for her sandwich and someone was available to go in the kitchen to get some for her. I would think they could get you a to-go container if you asked. Also, when you preorder, you still have to confirm your order when you arrive and you can make changes. You could check with that person to see if a to-go box will be available and remove the cupcake from the order if needed.
