Sure you can. The biggest drawback is training legs, which typically require higher weight. What you can do is 1 legged squats and lunges for quads, and "good mornings" for hamstrings. Calves can be trained 1 leg at a time as well. As far as upper body goes, dumbells will be fine.
Listen to this man, he's correct. It will be extremely hard to do legs b/c you need such a higher weight to work them out on.
If you want my honest opinion, I think you can do it, but it's highly inefficient AND dangerous. Inefficient in that, training each leg one at a time is going to double your workout time and use up more energy. Dangerous in that, you have a higher chance of dropping the weight when doing legs. For instance, when squatting, you most likely will have to be holding insane amounts in each hand. Deadlifting may not be as bad, since you don't need as much weight (maybe up to 400lbs). I legpress 900+ pounds on the sled, I don't know how you would simulate that though?
All in all, you will have to buy a set of dumbbells from 125lbs in 10lb increments up to 200lb, and even that may not be enough for squats. If you are changing out plates on the dumbbell, either you will have to put 45lb plates on it which are usually pretty big, or use 25's and extend them out which would be clumsy.
My advice would be to buy an Olympic squat rack, and a barbell plates for deadlift, romanian deadlift (hammy's), and squat. Your workout will be more efficient and alot more safe than dumbbells for legs (Upperbody, you can do everything with dumbbells).
