No, intelligence is a description of behavior, not stuff.
As a crisp example: a newly dead person is almost exactly the same stuff as an alive person, but has no intelligence at all. Not a little less, as the difference in stuff would suggest.
I reckon there would probably still be some if else system going on the body of a newly dead person.
