Aluminum cans are amazingly thin (roughly 0.005"), and are highly engineered because of that. Part of the reason most aluminum beverage cans have a concave end is as a safety against expansion.
With travels to California and Mexico I regularly pack liquids in my checked luggage (Hooray Tequila!) The worst that has happened to me is seepage around the cork or stopper. I am guessing the bottle was upside down and the air pressure pushed out the liquid around the seal.
Just don't wrap the soda in any precious clothing and I'm sure it will be fine.
