Technically, sure you could point to how important she was in the actual plot, yadda-yadda. How did it feel, though? Was there electricity? Like we have to see where the relationship goes or something will feel lacking? That's why she's interchangeable.
Are you serious? Some of the last lines in the movie were "...he misses her, the mortal." and "Can you see her? Yes, She searches for you." and the movie ends with Thor smiling at that thought. She is absolutely essential to the next movie, they are trying to get back to each other desperately.
