Abso-freaking-lutly. The permitted range for the CG (longitudinally) — denoted as "% of MAC", for Mean Aerodynamic Chord — is quite narrow, and you prefer to stay away from the "edges" of that range whenever possible.
The distribution of pax and baggage are chosen so as ensure its within the range. IOW, they don't book Row 1 then 2 then 3, etc, — sold seats are sprinkled across the aircraft as it's filled.
I've been told when the flight attendants are moving forward and back with the beverage service you can watch the trim wheel turn as the autopilot maintains correct AOA.
