If the turtle and crab are the same size, and the tank is quite large then I don't see why not. Although you need to regually monitor the water conditions as crabs are a lot less tolerant to ammonia/nitrite build up than turtles. Actually the turtle couldn't really give a toss.

If you have a big enough tank with enough hiding places, pH of around 7, you can keep virtually any fish together as long as all the fish are around the same size and these two groups of fish are avioded:
Serrasalmus
Tetradon(figure eights and dwarfs are the
exception).
I keep a successful community of fish in a 4 foot tank including the following families:
Cichlids, tetras, loaches, gouramis, barbs, rainbows, livebearers, killiefish, catfish, puffers.
