the legacy tag that is in ur character selection is just there to make u notice you are eligible to the Legacy only when 2.0 starts.

So when 2.0 have succesfully launch, you will be a Legacy member, which entitled to the forever discount of 9.99/month, and creating up to 40 characters, max per world is 8 characters and a special looking chocobo mount

so if you are asking "I saw the legacy tag on my character screen, can i now create 8 free character in 1.xx" the answer is "No"
