I believe they'd be the same on both sides of the Atlantic.
Otherwise identical in meaning, the reason I suggested the other phrase was for fluidity. It sounded more natural to use "I can't do anything."
In some instances, there is a difference between the phrases. If you were presented a choice of tasks to perform, for example, you could say "I can do nothing" and mean that you will not perform any of the tasks laid before you. If you respond "I can't do anything" to the same invitation, that would mean you are unable to perform any of the tasks.
