Indeed, exactly that, Royal Mail say if you don't have space for both
the Thoroughfare and the Dependent Thoroughfare, use the Dependent
Thoroughfare (sub-street) and leave out the Thoroughfare (main street);
the post town / dependent locality / postcode will do the rest. 

Using addr:housename for the substreet is definitely a bad idea, as an
address could actually need both: "Mon Repos, Rose Cottages, Green Lane"
