Authorised service providers may use the dent as an excuse to refuse a repair under warranty (exactly the same happened to me, when they refused to replace a screen because of a similar-sized dent)
I wouldn't count on even Apple's service in North America, let alone other countries. Maybe you should double check if it's going to be a problem in Apple Store beforehand? And maybe document the issue so that you have a proof it happened now and not right before you went to a service centre (hopefully you'll never have to)?
