Yes, but only distantly. You have to go to a pretty high level of taxonomic classification before you find a common taxon. They are both in Phylum Arthropoda, but part of different subphyla, which means they are quite distant. Crabs are members of Subphylum Crustacea, while scorpions are members of Subphylum Chelicerata, and are more closely related to Spiders than they are to crabs.
