I doubt there is any connection with the caves. Chrysalis states it used to be a place for greedy _unicorns_, so it probably had no connection with the Crystal ponies.

Further, in the song it is stated that the Crystal ponies have their own kingdom (and anthem), which would make it weird, if said kingdom was right next to or beneath Canterlot.
