Hello there,
If your Wikipedia has any objection, it is likely that it will nto be indexed by Google, because it is not a reliable page. For your page to be free of any objection, you have to make sure that your wiki abides by all of the guidelines and instructions set by the wikipedia community.
The most important is that you have provided references of your company's name that wikipedia considers an authentic third party source. For example, an online article on "theguardian" or "CNN". If you have met this requirement, there is no way that anybody or anything can stop you from having a clean, indexed wikipedia page.
Thank you!
Nayab K.
