Alternative Host without host ever joining

If an alternative host starts a meeting that I organised and with my personal zoom code and I don't join it, can I then use my zoom account to join a different zoom whilst the one organised is going? I have double booked myself and have scheduled a zoom for a lot of children using my zoom code. I can't do the zoom so I wanted someone to take over for me without having to change the code with the participants. Whilst that zoom is going on, I will need to use my zoom account to log into the other meeting.
