Yeah mate, there's a chance to loose it at it has a different configuration blockchain. The system will invalidate the transaction, but I'm not sure if this will go back to the original address or will loose. Interesting question, but this one isn't new, Im sure there are people with high curiosity to try this out just to see what would happen. My bet is it will return as the transaction is invalid to process. Hope every chain is like that. Cause inevitable to make mistake sometime and losing our precious coin that way is really heart breaking.
