Opinions will be all over the map on this one. While you won't hurt anything changing it earlier, you also certainly won't hurt anything going by the schedule and doing the first change at 600 miles. Everyone has their own belief, but mine is that you are needlessly spending money on oil if you do the change earlier than 600. But hey, if it makes you happy, oil is cheap.
Some vehicles, like my wife's 2014 Honda CR-V, are very specific in the manual, and say that while any interval is fine after break in, DO NOT change the oil early when new, and that it's important to leave the factory oil in until the first scheduled change.
