Johnson wants Spurs to drop their legal action over the Olympic Stadium and has promised the club £17m to help develop a new ground next to White Hart Lane.
The funding has attracted the wrath of Leyton Orient chairman Barry Hearn, who likened the offer to a bung.
"Boris has made his move to try and placate Tottenham and if I'm being cynical, it looks like a bung just to get him out of a court case," Hearn said.
However, Johnson's office have denied the accusations.
"To suggest that the proposed offer from the GLA and Haringey Council towards Tottenham Hotspur is an inappropriate use of funds is entirely inaccurate.
"The discussions that took place yesterday outlined a comprehensive plan for the regeneration of the area that is in the interests of not just the club, but the residents and businesses of Tottenham."
Spurs recently revealed that they have been granted planning permission for a new development next to White Hart Lane.
