Hello!
I would advise using different stories in the interview as much as possible. You only get a limited amount of time to present yourself as a candidate to the interviewers and will only be asked a few behavioral questions per interview, so you ideally want to use different stories so you can showcase more experiences that you've had. It might be ok to use the same position but describe different experiences you have had within that (e.g. if you were the leader of some student organization for multiple years, that could give you multiple experiences that you could split over several distinct stories), but in general I would steer towards using different experiences to show that you are a multifaceted and enthusiastic candidate with many interesting experiences.
That being said, you may not necessarily be asked about both your entrepreneurial drive and team leadership in an interview, so if you think this experience provides your best story for both, it's ok to prepare it as a response for both and just use it for whichever questions comes up. Just be sure to have an alternative story in case you do get asked both of those questions.
Hope this helps, and feel free to message me if you have any more questions. Good luck with your interview prep!
