Yes, you can use the tablebases IF it runs as a windboard adapter engine. It doesn't use its own book (rather the general.ctg or whatever book is specifiied). W/ Crafy 16.3 I have gotten the tablebases to work nicely, yet if the position is drawn crafty will put in the log "drawn at root, trying for a swindle" (drawn it the tablebase that is) otherwise it will show a mate in n.
