That's certainly fair (and to be clear, when using Americas in English, the phrase is the Americas, including the definite article), though it would also be fair to restrict it to the English language, as names change depending on the the language. For example, Hungary in English is Ungarn in German (Deutsch) and Magyarország in Hungarian (Magyar). I'm not going to insist that Germans should use Hungary or Magyarország auf Deutsch. As a first approximation using Google Translate, American translates as americano in both Portuguese and Spanish, while Mexican and Brazilian, for example, translate as mexicano and brasileño (Spanish) and brasileiro (Portuguese), respectively. I didn't find a way to limit this to particular locales as would be appropriate. These types of things can be subtle, and I'm interested to hear from good sources that can provide more insight.
