No, it is not ok, it is potentially very dangerous because the two-wire cable has no earth with it. The earth wire is an important safety component that comes with a three-pin plug. An exception can be made for certain low-power appliances that have double insulation. This includes TV sets, radios, and table lights provided the mounting is plastic and not metal. These appliances are commonly sold with a twin-wire cable but often with a three-pin plug on the end of it. The three-pin plug in this case often has a plastic 'earth' pin and it is safe to replace it with a two-pin plug.

In an electrical socket, there are three holes. One is a hot wire, one is a neutral wire, and one is a ground wire. Usually, the hot wire is black. The neutral wire is white. And the ground wire is green. Motors usually have three pin plugs. Other items also have them. When a motor has a three pin plug, the body of the motor is attached to the ground. If a spark goes from the electrical wires to the body of the motor, it will go harmlessly to the ground and not hurt anyone. On a two pin plug, usually one pin is larger than the other. The larger pin goes to the neutral or white wire. It is also grounded. That way if there is an electrical short in the device, it should not electrocute the person using it.
