Nope. Well, not without some extensive DNA meddling, to the extent that it may LOOK like a dinosaur, but it really isn't. Putting aside the DNA issue (see other comments), there's also environmental issues - the atmosphere during prehistoric times (I'm not an expert here, so excuse the vagueness) was far more oxygen-rich that it is now. If a real dinosaur managed to time-travel to our present time, it would die of asphyxiation like a fish out of water.
