Technically you can if you activate the 10 day MoP trial.
What i did was the following: i activated the 10 day trial. I used Kicks Jade Forest profile to do all the quests in jadeforest. After that you cant continue as it will bring you to VotFW and you need to be 86 to accept quests there. You will however have collected some nice gear while you was questing. I had no trouble fighting mobs in Jade forest or VotFW.
So if you are after herbs and GI ore, you will be able to collect that in mentioned zones atleast, although you will be farming with groundmount.
You can even tick the option to collect herbs and mines in the settings so you will be collecting those while questing in Jade Forest.
