I wouldn't, if I were you.
First, you run the risk of a chemical reaction between the nail polish and the existing lacquer. This is a remote risk, but a risk nonetheless. It probably wouldn't happen, but if it did, you'd ruin the rest of the finish, and potentially the trumpet itself.
Second, I can't imagine that the two different finishes will look the same after the paint has dried. The nail polish might have more or less of a shine to it than the lacquer does, and if that's the case, it'll be horribly obvious.
Third, the nail polish would probably streak. The surface of your nails is much rougher than that of a trumpet, and this would most likely make it very difficult to apply the polish without it streaking. Not only that, in order to make sure that the nail polish (paint, in essence) sticks to the surface it is applied to, you have to make sure that the surface is rough enough to grip the paint. I'm pretty sure you wouldn't want to take sandpaper to your lovely black trumpet.
Fourth, it would only be a very temporary fix. Think about how quickly your nail polish starts to chip after you've put it on your nails.
I could probably think of more reasons why I, personally, wouldn't do it. Take the extra expense to get it relacquered professionally - you'll be glad you did in the long run. If you can't afford it right now, save up and do it later. In the mean time, you can take some steps to make sure that it doesn't get any worse, like buying a nice hand guard, and being sure that you wipe the trumpet down after every use so that the oils from your hands doesn't have the chance to just sit there and eat away at the rest of the lacquer.
