The best way to find out is to contact Verizon. The worst they can say is no.

I would think if you have one of their new Shared Data plan the answer would be yes, but I am guessing you also want them to get you a reduced cost Tablet Plus, too?

I doubt they will let you keep your present account if it is not one of the new type, as they are phasing out grandfathered accounts. But heck anything is possible.

 

Verizon doesn't have the tab plus. They have the 7.7 galaxy tab, I believe. I think VZW stopped subsidizing their tablets so you'll have to pay full retail anyways which means you can keep your plan and switch the devices.

 

They also added the Tab 2 yesterday :

The 7.7 is better than the 2 7.0 in some ways... better res screen and faster SOC. you should look into the 7.7 before deciding.
