Veto just means "I forbid". It is perfectly fine to use it outside the context of the President denying his consent to legislation.

For example I could, and have, vetoed a resturant in a discussion of where to go for dinner.

In this case a decision of the International Trade Commission is presumptively valid unless the President, or his designee, forbids the ruling from going into effect -- or in other words, unless he vetoes it.

These are all fine uses of the word.

However, when you use the word "veto" in the context of the President, it implies a certain set of actions that have taken place. It actually encourages people to think those events took place, when reading the letter makes it obvious that they didn't.

This is all moot now, since they changed the headline from "Obama vetoes..." to "Obama Administration vetoes...".
