I am sure that there is no consolidated list available to the general public. Each business jet manufacturer wants to keep his client list confidential, for competitive/marketing reasons.
Most biz jet owners keep their aircraft paint schemes non-distinctive. Most do not put their company logos on the tail or fuselage, some do not add US flags if they do a lot of international flying.

Boeing Flown: 701,702,703;717;720;721,722;731,732,733,734,735,737,738,739;741,742,743,744,747SP;752,753;762,763;772,773.
