Can a Dash 9-44CW be used to pull a passenger train?
I remember Amtrak used a Dash 8 on one of their passenger trains and so I was wondering whether a Dash 9 could be used?

As part of a multiple unit lashup with another loco that is HEP equipped (Head-End Power, to supply power for heating, lighting, and A/C to the passenger cars), probably so. On its own, not if the cars are to be occupied unless:
A) The loco is refitted with Head-End Power capability (can be done at the factory, for $$$), or B) The cars are equipped with their own onboard generators for heat, AC and lighting (many privately owned cars are), or C) There is a dedicated HEP generator car in the consist (or a steam generator car for older-spec [pre-HEP] passenger cars).

Passenger trains can be pulled with a freight unit when needed, although, as noted above, the unit would have to be passenger operation equipped to be useful for anything more than a rescue service. I've seen the SW Chief being pulled by 2 BNSF Dash-9s after the P42s crapped out! The remaining P42 was used for HEP. The -9s work, although their speed is limited to what the freight units are geared for (about 75MPH), and the train line air brakes have to be set to a higher psi for passenger service, as compared to freight service (110 psi vs. 90 psi). Another factor is the locomotive weight and what its designed for. Amtrak locomotives are lighter in weight than freight units, as they are designed to accelerate more quickly, and stop and go more frequently. The -9s are designed to lug heavy tonnage at moderate speeds over long distances. However, the Dash-8s Amtrak has are a spruced up freight model, and seem to have proven themselves useful over the years. Anything bigger would probably be unnecessary, though. Hope this helps!
