Yes & no.
No - because in the current condition you're using superglue to attach the Backpack to a cockroach and removing it you'll damage the bug and possibly the board.
Yes - if you're using a double-sided tape or an adhesive putty to attach the Backpack to a cockroach. Then you can easily remove the Backpack by carefully removing the tape or adhesive putty and desoldering the electrodes.
