Yes, it is possible. Like @Yetive said, you will need to communicate asap.
If your transfer hasn't been processed yet and you are still linked to your original store, your original store HR can just notify the other store that your plans have changed and you will no longer be going through with the transfer.
If your transfer has been processed already and you are now linked to the other store, a form can be submitted by HR to transfer you back to your original store as long as both stores are okay with it.
