I doubt the magnets inside your containers would cause an unplanned uncoupling. Even riding low in a well car, they wouldn't be close enough to the couplers to interfere with them. Also the container magnets are likely "aimed" downward, in terms of their magnetic field. Uncoupling magnets create a sideways field in order to swing the steel trip pins out to the sides. It's not that easy to take any old magnet and uncouple Micro-Trains couplers. The magnet(s) need to be set up right.
However, it may possibly be that a magnet-equipped container might try jumping upward, or trying to stick the car down on the uncoupler, (depending on magnet orientation) when it passes over one. Only trying will tell for certain, but again the vertical vs. horizontal field orientation would probably prevent this. Try it and see.
