If you do disconnect the charcoal canister (not recommended), the vent line from the tank has to be left open. I've seen tanks that have imploded when capped off. That happens mostly when the tank is dark and sitting in the hot sun, and have imploded as it cooled off. Very rarely have I heard of one expanding, bulging out, curling the sides upward.
