Fernandes, the boss of Formula One's Team Lotus, met Warnock on Saturday after watching the newly-promoted team win a pre-season tournament in Bergamo, Italy.
QPR last week announced they were in discussions with potential new owners, with the interested party since revealed to be Fernandes.
He has reportedly been negotiating with QPR co-owner Bernie Ecclestone and the F1 supremo's business partner Flavio Briatore.
Warnock was keen to meet Fernandes to discover his plans and he told the Daily Mail: "Myself, Flavio and Tony all had a positive chat after the match on Saturday.
"We've already spoken about possible targets and he is a very positive chap."
Fernandes last year lost out to David Sullivan and David Gold in a battle to buy West Ham, but he remains keen to invest in football.
In March, Ecclestone suggested he might be interested in selling his 69 percent stake in QPR for £100 million ($164 million) and the club entered into talks with an unnamed group, with due diligence taking place.
Those discussions failed to reach an agreement, but QPR last week released a statement revealing the Championship winners had started "preliminary discussions with a different party".
Almost a third of QPR's stock is owned by the Indian family of metals billionaire Lakshmi Mittal.
In May, vice-chairman Amit Bhatia, Mittal's son-in-law, resigned from the board after a disagreement over ticket-price increases and changes to club management.
