Basically 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 your 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.
