Well, yes, but you can only climb up to a certain point on the social ladder. In fact, adapting to corporate culture guarantees that you will never be a member of the highest class. You may reach the upper middle class, but you will never become a member of the upper class because the upper class not only does not work (they don't need to), but they look disdainfully upon people who have to work, especially people who sell things, because they consider selling things for a living to be vulgar. People who come from the corporate world will almost always, even if they aren't conscious of it, have middle class tastes, and middle class speech mannerisms. For example, Corporate America loves modern design (because it is boring, and thus cannot be offensive) and uses lots of euphemisms. Members of the upper class hate euphemisms, and consider saying "Fudge!" to be much worse than saying "Fuck!". This goes against everything a Corporate America drone has been taught. Social norms in the upper class are much different than social norms in the upper middle, and other classes. The obfuscatory circumlocutions known as "HR speak" or "BS" are reviled, and so are foolish compliments. If you are at an upper's house and praise their furniture, you could be ejected from the premises. Why? Because it is a given that an upper will have good furniture, and compliments about it suggest that this may not be the case, which is offensive.
Because the things we do, say, and the values we have are often subconscious, it takes a concerted effort to change them and it is almost impossible to do so. The things that determine your class cannot all be written down into a book. Even if you do pretend to be an upper, at some point you will commit a faux paus that gives you away.
