It CAN be done, friend of mine scratchbuilds N scale locos that small or smaller and gets decoders int hem. You need to look at the tiniest Z scale decoders. ANd you need to be comfortable working on such tiny things with a magnifying visor and a VERY fine point soldering iron. I consider myself to be pretty good at soldering, but when he shows me a new loco, I can't imagine how he got it all to fit in there, with tiny short pieces of wire connecting things.
Here is one article I found: http://www.trainbuddy.com/Reference/decoding%20Engines/N440.htm

Who made the models, and how old are they? Decoder installation can be a simple plug-in, or a more difficult job that involves soldering and machining away material to make space for the decoder. If you want a sound decoder, you will need space for a speaker, too.
Steam engines can be easier, as the tender may be used to house the decoder.
Do they run well on DC? If not, they won't run well on DCC, either.
It takes an iron man to play with a toy iron horse.
If someone can actually get a sound decoder in one of those AND have it still able to pull a reasonable train, they will be the king of DCC. The only way they pull anything so as it is is because the boiler is mostly weights.
About the smallest decoder available today is the DCX76zF decoder made by CT Elektronik. They are just under 1/4" square and about 1/16" thick ....

They ARE a European company, but if you do some searching, they are available on this side of the pond for around $40 each.

Bryan at Streamlined Backshop sells one of the smallest decoders available:

Same decoder as Mark mentioned in his post. Streamlined Backshop is $41.00 vs about $47.66 for the one from England (at current exchange rates).
I'd like to know who made the engines too. If they are Bachmann I have some experience adding power pick up to the driver wheels. That would improve DCC performance.

I'm just a dude with a bad back having a lot of fun with model trains, and finally building a layout!

Dave they are Bachmann and any help will be helpful
