No, there are many other parts on the engine that can affect mileage but the catalytic converter is a passive device and, if new and clean, cannot affect the way the engine runs or the mileage it gets. Think of it as a filter, althought it's actually a lot more complex than that, if it lets the exhaust gases flow throught without any major obstruction then it can have no effect on the car's performance.
