Vinicius, who received dual citizenship on March 10 and has been playing for 2015 Hungarian champions Videoton for the past six years, was included in coach Bernd Storck's 27-man squad for the Group B encounter in Lisbon.
There was no place for Chicago Fire striker Nemanja Nikolic, however, as Hungary prepare to face Portugal for the first time since they played out a thrilling 3-3 draw in the group stage of Euro 2016 in June.
Hungary are third in Group B with seven points after four games, two behind second-placed Portugal and five adrift of leaders Switzerland, who have won all of their matches.
Hungary will play a friendly against 2018 World Cup hosts Russia on June 5 in Budapest, the Hungarian Football Association have announced.
