If the can is metal it wont matter if the soup is contaminated because metal + microwave = fire. And if it was in there long enough it probably would contaminate the soup but even if it didn't, don't microwave it out of the can.

May sound obvious but open it first otherwise BANG

I have heated soup and other canned foods over a fire while camping. You have to watch to see if the can has a plastic lining and it doesn't become damaged while heating.

Canned foods are typically heat processed after sealing in the can so as long as it is controlled there will not be a problem.
