It is confusing to read. Basically Icahn says Trump offered him a position Icahn refused, then later told Trump he accepted the Sec of Treasury position.
I might be wrong, but I got the impression that Icahn was kind of joking and kind of flattering Trump.
Trump has said that he would like Icahn to work in his administration but didn't mention in which position. Icahn seems to be saying he wants to be Treas Sec.
Trump said "I think Cark Icahn would make a great Treas Sec." He didn't officially offer him the job but was just trying to share his ideas of personal.
Icahn said that he declined because he doesn't get up that early.
In other words, it was just banter.
They are good friends after all.

After last night’s debate I decided to accept
@realDonaldTrump offer for Secretary of Treasury.
