No. "Hispanic" refers to people from Hispania and people descended from people from Hispania, Hispania the Latin name for Spain. The Latin name for Portugal is "Lusitania," so correspondingly, they would be Lusitanic, not Hispanic, but nobody actually calls them that. They just say Portuguese. It's because people of Portuguese descent aren't Hispanic that the term "Latin American" was coined to also include people from Brazil, people in the Americas who are descended from Portuguese ancestry, ethnicity, and/or culture. "Latin American" is a broader term that would includes both Portuguese and Spanish descendants. What's ironic is it's as much of a misnomer as "Hispanic" is since the people of Portugal and Spain didn't descend from the Latin people, who were located in what is now central Italy. Personally, I think they should've gone with "Iberian Americans," as Portugal and Spain are located on the Iberian Peninsula and together comprise the entirety of the Iberian Peninsula, well except for the 2.6 square miles of Gibraltar that's occupied by the British and the 180 square miles that is Andorra, which may or may not be on the Iberian Peninsula since it's nestled in the Pyrenees Mountains between Spain and France, which is where the peninsula ends.
