Depends on who you ask, and who you are.
[i]Q:Another major criticism of the Starting Strength program comes from squatting three times a week. People say it's "bad" for the lower back. Just like they say you shouldn't squat and deadlift in the same workout.
A: Sure you can... if you're a novice.[/i]
If you're doing a form of "total body training", meaning you're doing full body workouts every session, the least complicated method will be to choose one exercise per movement pattern (horizontal push/pull, vertical push/pull, quad dominant, ham dominant) and you'd want to minimize redundancy.
Doing a full clean (from the floor) and a squat or deadlift on the same day will be redundant, and unnecessary. You'd be better served choosing variations of those exercises. For example, hang cleans and sumo deadlifts or full cleans and lunges (instead of squats).
Or if your heart is set on working those movements together, you'd need to vary the set/rep scheme. On the days you're working the clean heavier with low reps, you'd lighten up the squat/deadlift and use a moderate rep range for those.
