O Tenente Ro fala de Tuvok no episódio TNG de ataque preventivo?

Não, Tuvok não treinou na escola Advanced Tactical Command durante esse tempo. Ele tinha acabado de sair da Academia da Frota Estelar depois de 16 anos em 2365. Então era improvável. Ro Laren teria treinado com Tuvok na Academia, mas sua posição na época ainda era Ensign.

Ro Laren entered Starfleet Academy in 2358 and graduated with the class of 2362. (TNG: "Conundrum", "The Next Phase") - Memory Alpha > Ro Laren

Não. De acordo com a Memória Alfa , ela realmente quis dizer Chakotay:

The lieutenant commander whom Ro Laren refers to as her instructor at Starfleet Advanced Tactical Training in 2369/2370 who joined the Maquis was intended by the producers as a reference to Chakotay of Star Trek: Voyager (Star Trek: The Next Generation Companion). This suggestion is included in Ro's biography at StarTrek.com. That intention was contradicted in VOY: "In the Flesh", where Chakotay stated that he resigned his commission on March 3, 2368.
