If a new CEO of Coca-Cola made a speech announcing a proud partnership with the KKK or Al Qaeda and ran an ad campaign informing the public then sure I imagine that'd be a lawsuit. Coca Cola would never disassociate its brand, every reasonable person could predict the forthcoming disaster and every shareholder would want to recoup their losses.

So yes, CEOs do have a duty to avoid saying certain things, sometimes. Does it extend to Trump? Not quite, I don't think, but the very idea of it is not unreasonable.
