Yes you can. You will be over driving your tube which would mean that the tube life will be lowered by quite a bit. If you are ok with it than its not a problem the lamp will definately run with a higher rating Ballast.

I hope you are using electronic ballast and not electro - magnetic / coil / inductive ballast.
This to me i.e. when we have the same wiring of electronic ballast we are not overdriving. Just that we are underutilising the capeability of a ballast.
In a simple DC power calculations we know that power is IsquareR, note that voltage is a constant parameter, Since the only path in a normal tube connectivity is the tube itslef, There is no way to increase the current flow Â ( except for the matter of fact that some passive electric parts are added to do this which we are not doing ).
I suppose this also applies for AC currents, But one should calculate the impedence here rather than resistance. Since the current is the same and the impedence is the same the power consumed by this normal wiring will be a factor specified by the tube.
Overdriving is chaning connectivities and making current flow through multiple paths and join the same path at which they enter the tube in lay mans terms.
