Yep, in the early issues of Iron Man Vol 4 and later referenced in some issues of Invincible Iron Man Vol 1.

Well, it's easy. Any previous reference of Vietnam can be easily ignored or you can imagine whenever in an old comic (under the context of Iron Man's origin) it says "Vietnam" it actually says "Afghanistan".

It's no big deal, Stark's origin had been already changed to the Gulf War because of the Marvel moving timeline.
