You can, but keep in mind that the noodles will get quite mushy if you cook them completely before freezing.  Ideally, it’s best to freeze the beef mixture before adding any noodles.  That way you can cool completely, transfer to an airtight container and freezer for up to 2 months.   Once you are ready to use your frozen goulash, you can cook the pasta separately while you reheat the beef mixture, either in a pot on the stove or in the microwave.  Mix them together, add your cheeses and garnish and serve.
