These are a selection. Even a short search among the giants reveal an ambivalent attitude to the position - there are companies whose president had been dismissed, ones who pointedly note that the position is vacant, and a number where the structure has no single president; some having regional presidents, others a group of section vice-presidents looking after different aspects of the business.
There are also a few deemed 'CEO and President'. I've listed Tillerson but Wal-Mart and Toyota/Toyoda are other examples.
