After complaining to referee Calum Murray in the tunnel about his performance, with the Hoops a goal down and defender Cha Du-ri sent off, the Lurgan man was ordered to the stand.
The Parkhead boss has allegedly breached rule 203 which pertains to "misconduct at a match by dissent, the adoption of aggressive behaviour towards a match official and the repeated use of offensive, abusing and insulting language" and has until next Tuesday to respond.
However, Lennon's account of the incident is at odds with the complaint.
"I spoke quite quietly and coldly to the referee in the tunnel," said the former Celtic skipper after the game. "I didn't swear and didn't point any fingers.
"I told him I wasn't happy with his first-half performance.
"I was speaking to the match delegate after the game and their version of events are different from mine but I've got witnesses to back me up.
He continued: "Alan Thompson (coach) and our PR person was there, and a couple of other members of staff and players."
Lennon watched the rest of the match on TV in the media room after Celtic's security staff advised him against sitting in the stand.
The Scottish Football Association have set the Principal Hearing Date for Thursday 19 April but the SFA's Compliance Officer, Vincent Lunny, and Lennon have another matter to clear up.
Lunny has already written to the Celtic manager asking him to explain his comments following last week's 1-0 Scottish Communities League Cup final defeat against Kilmarnock at Hampden.
It is understood Lennon described referee Willie Collum's decision not to award the Hoops a late penalty as "shocking" and "criminal".
