Narrative:

Received an ACARS alert at top of climb to go back and check 2L for a can that they thought they pulled off. First officer (first officer) went back and verified that there was in fact a can in position 2L. [Dispatch] then sent new west&B numbers for zero fuel weight (ZFW)/zero fuel weight center of gravity (zfwcg) of 319.7/17.3 vice the original 317.2/8.7. During the approach; at 180 kts with slats extended we got a brief stick shaker. Then after configuring; the vref was 140 kts which should have given a 145 kts vapp; but that was well below the approach band on HUD for flaps 35. We added 6 more knots to 151 vapp to keep the arrow in the middle of the approach band. Landing was uneventful at 1.2 gs. Landing runway wind was 140/12. Load crew and the person responsible for weight and balance did not communicate.

Title: Air carrier First Officer and Dispatcher reported receiving new weight and balance data in flight after verifying that one load position was filled. After experiencing a brief stall shaker warning on initial approach using the calculated Vref; the crew added additional speed to Vref.
