No there is not, in most companies. In most firms, if you try to be an "intrapreneur" while the middle manager to whom you report has to deal with typical corporate dreck, you'll break this "Law of Power" (Never Outshine the Master): http://www.youtube.com/watch?v=WMy8Tf-zCag Then you get fired for being "distracted" because the perception is that you care more about your career goals than your manager's. (Of course, this is usually true for most people and there's nothing wrong with that, but one can't be brazen about it.)

There are benefits to working in larger companies, but the idea that one can just decide one day to recast his job description to "intrapreneur" is laughable for most people. The people who have jobs that would allow that (in small or large companies) don't need to fall back on some templated concept.
