Since these two exercises require the glutes and quadriceps as major muscles, would you overtrain them if you did squats and deadlifts in the same work out?
It is a good thing to train your legs with squats and dead lifts in the same workout session. You should be grouping muscles that normally work together into the same workout (chest shoulder tricep, legs, and back and bicep). This is great because it decreases the number of times your need to workout, decreases your workout time, and increases your muscle fatigues. This is because when you are working one muscle group, you will also be working other groups in that area. The point of working out is to fully exhaust your muscles as much as possible and as quickly as possible so you can get out of the gym and start resting that group for the next time you will stress them. If you worked out that group on two different days they would still be recouping from the first time you stressed them and thus wouldn’t be prepared for the other exercise (overtraining by not allowing enough rest in between for your muscles to heal). Remember that building muscle requires proper rest for your muscles.
I suggest you group your squats and dead lifts together along with super-sets of leg extensions and hamstring curls to really work those muscles. Also always remember to have good form, especially when you are performing squats and dead lifts.
Good Luck
Basically, we need to define "overtraining." Overtraining is when you do not give your muscles enough time to recover before you use them again, therefore leading to breakdown of the muscle. For example, doing squats one day and deadlifts the next. But when doing them in the same workout, you are only training them once and the body does not expect to begin healing until the workout is well over. So by all means, do both. In fact, your goal (for strength and size at least) should be to work your muscles to failure, so do as many exercises as possible. Throw in some leg extensions and lunges to further kill your quads. Just make sure you space out your next leg day a few days out.
