I'd think so.
They could ... though I'd think an existing engine with a passenger car or two would work just as well; or better yet, a 40-minute bus ride. It's not like you'd need dining, cafes, or sleeping.
Though I'd think more likely, the short connection would be from Matheson to Timmins, with most of the train going up to Cochrane to meet the Polar Bear Express.
Though perhaps a simpler idea, would be to run the train from North Bay to Timmins, then take advantage of the cab cars, and just back it up to Porquis Junction, and go then go forwards the 45 km to Cochrane.
Though if we want to go into fantasy map world, the short train to Matheson, could extend in the other direction and restore service to Kirkland Lake and Rouyn-Noranda and Val-d'Or, to meet the VIA train in Senneterre.
(which makes me wonder why wonder why the Senneterre train runs some 650 km to Montreal, but doesn't extend another 60 km to Val-d'Or and then 100 km to Rouyn-Noranda. (from there it's only 85 km to connect to Kirkland Lake and the existing ONR Northland) (to answer my question, it's probably because that's where the roads begin, so no TC requirement to continue service - but ditto for Toronto to Timmins/Cochrane)
