Depends on the bb width and the rear hub chainline, but usually the inside ring on road cranks has a chainline close enough to standard track chainline to not be a problem (41mm vs 42mm IIRC).
You'd just need narrower chainring bolts and a chainring/chain width the same or bigger than what's on the back.
7400 is a really nice crankset, would be completely fine for a commuter/beater.
