Absolutely! The music predated the term. May I suggest checking out Big Joe Turner's Jump Blues arrangements which he reportedly gave to Bill Halley, and to what Big-band Swing Musicians did with Boogie Woogie and Jump Blues. Of particular note are Erskine Hawkins' "Hawk's Boogie" (1946) and "Uproar Shout" (1937). Some might say Hawkins' variations of Jump and Boogie were the first Rock & Roll arrangements. Also, Fats Waller's playing laid considerable ground work for Rock & Roll.
