I do not think it is synonymous. Running a company means pursuing profits, but it does not mean you have to ignore all other considerations. You can have ethical limits, server customers, look after the interests of your employees, reduce your environmental impacts etc.

Greed means running a company without due consideration of these things.

IN this case the explanation I am suggesting is even less synonymous because by putting short boosts to the share price over long term profitability is not (in the long term) even serving the best interests of the shareholders.
