Yes the voltage ration will hold. You can even swap the secondary and primary sides but there may be differences of a few percent because the listed voltages include a margin for internal losses. What you cannot safely do is exceed the current rating of any winding even though the total power is within specifications. This is because excess current can saturate the magnetic core which can result in suddenly lower impedance and bad things will happen. In the example that you gave, this would mean that you would only be able to safely get half as much power from the transformer.
