Can you add the M5stack Core battery (the module with the red base) to a Core2?

I was thinking of extending the battery life of the Core2 even further by adding the battery module. Would this work if I was to remove the mic expansion board on the core2?

I did the test, it works with the red battery module link text
but I prefer the M5GO2, because it adds a port B and C

Thank you very much!
