I guess it depends on your definition of necessary. No it is not necessary for the car to run, perform well and stay cool ... as long as you check coolant level now and then. Also ... if your radiator does sometime over flow a bit ... the tank would keep the coolant off the underside of the car.
But no, it's not a critical component.
