I think Tesco use the O2 network, if I'm correct you will have no problem using your O2 iPhone on the Tesco network.

Yes, you can, but not vice versa.
That said, problems arise if it is locked to some network, not registered. If the phone is unlocked you can use any sim

Aside from the issue of whether the phone is network locked, I think iphones use different size SIM card.

Yes, but iPhone 4 and 4s only. Also you can cut extra plastic from a normal sim to make it micro sized.
