Yes of course! They work really fine as separate workouts.
I started out doing just the cardio workouts (KenpoX and CardioX) every other day and doing my own (easier) strength workout and still made a lot of progress in the first month.
The second month I switched from my own 30min strenght wokrouts to p90X strength workouts 2 times a week (Shoulder&Arms, Legs&Back)
I did a bit easier workouts in addition if I could find enough time. I've just made a blog post about loosing more than 14 pounds in 2 month using p90x in a modified way.
Of course it's put to the best use if you do the program in that exact way, but the workouts are really good on their own as well - intense, engaging and well-marbled. Just don't just one workout over and over each day.
I've recently started the Lean program, going on week 2 now. I'll most probably skip some workouts here and there, but it doesn't really matter so much in the long run. Good luck!

I arise in the morning torn between a desire to improve the world and a desire to enjoy the world. This makes it hard to plan the day.
