Can you clarify your question please as I read it differently to @pgn
If you take a refresh contract you must take a new airtime tariff too. So whilst you can use your current SIM, it will have a different tariff attached to it.

The short answer is no
You must take a tariff if you want a new phone unless you buy the phone outright
In that case there are much cheaper ways of buying rather than through O2.
