Positioning of elements in research paper
Your problem is that a term paper for university is not the same as a company white paper. You cannot expect to write a nice white paper ("What is a good way to present the introduction and discussion/conclusion in a paper which has to be easily read and understood by non-academics.") and expect your professor to grade it as such. The conventions for white papers and academic reports are significantly different (and I would honestly be surprised of the positioning of the conclusions are really the only required change).

I like Suresh's suggestion - produce two versions of the report, one for the company, which focuses on the results and implications for the company, and one for the university, which is written for an academic reader outside the company. The style may well differ, even if the vast majority of the content will be the same.
