Maybe never 'full' but I think it's highly likely he was very influential in the players which came to the club. It's important to remember the dire straits Spurs were in when he went there. Redknapp had the bargaining power not Levy. I think it's also likely that, eventually, Levy wanted to revert the structure of the club to the continenal model and and hence why the relationship deteriorated in recent times leading to Redknapp's sacking.
