Highly unlikely. Issuing securities at this level involves the board, internal counsel, external counsel, the underwriters (at least 5 here) and each of their respective in house lawyers and external law firms. They are all at risk, huge risk from any such intentional action. Further, even if TSLAs internal counsel was soft for the boss, the underwriters' external law firms care little about Tesla. They are hired independently to protect each underwriter on the hook (Goldman, Morgan Stanley etc) by identifying all risks, including come back risk. And if there was any fraud or misrepresentation to them....... it'd be the end of Tesla, SpaceX, SolarCity and our extended service agreements.
The offering proceeded because the collective position of all Counsel and Bankers involved, was that the absolute materiality tests failed.
