Yes you are still limited to 10.

And yes, just copy the formation and move the forward to winger or vice versa. They'll keep all of the same movements, except for any difference in how wingers behave compared to forwards.

If you want to save your formations and you are out of space, you could export them and save the string of characters to a notepad file. If you then want to use it again, just take the string and import it.
