Yes, you can tell if you know what to look for. It's easier to tell an old buck from a doe, than a young buck from a doe. There are many things you need to look for that add up to a buck track for sure.
Evidence it's a buck track include these things. The size of the track, (the bigger it is, the more likely a buck). The deeper the track, (heavy bucks leave deep prints in the ground). If it is more rounded, than pointed at the front (bucks wear the front of their hoofs by scraping more). If the track moves in a straight line, rather than meandering and stopping a lot. If the tracks point out away from the center line rather than align parallel with it. If you see a urine stain in the snow that is off to the sides rather than in the middle of the tracks. If you see antler tip marks in the snow where the deer put it's nose to the ground. And any other obvious signs above the ground, like antler rubs or broken twigs where a deer moved through dense brush.
Determining if a track was made by a buck or doe is a preponderance of evidence more than just what you see in one or two tracks. You just need to know what signs and evidnce to look for as you follow the tracks. There are some good books on the subject. Check out books by the Benoit Family of Vermont. They only hunt big bucks and they only hunt by tracking. They are considered the best there is.
Following the tracks and taking that buck, is a whole nother chapter in the book of tracking deer. And it takes much more experience and skill than just being able to identify the track as a buck. Good trackers have spent a lifetime learning the skills, and often they had an expert for a mentor. Tracking deer is an art that is almost lost amongst today's deer hunters.
