Since combustion requires temperature, as well as fuel and oxygen, can it become SO cold that comb. can not occur?

I would say so. Without a match you won't get the fire going. The products had to be brought up to temperature. Keep them below combustion temperature and you are safe.
Now that is just off the top of my head.

What do others think before they go and research it.

could (say) a lighted match be brought into an environment which was so cold that the oxidation process would be halted?

You try and use a match on a windy day! It isn't that easy to get combustion going. The wind cools the match and stops you bringing the rest up to combustion temperature, but in the process you have used your matches and there is not unlimited supplies of them. So how do you do it?
How do you get wet wood burning on a cold windy day? How are you going to get combustion going?

Possibly............... but please consider stuff like liquid oxygen @ around -200C;- you know, the stuff injected with kerosene that fuelled the F-1 Saturn V main-stage engines.
