Only if you think "Master of Business Administration" and "Chef" convey equal amounts of business administration skill. The exective board page linked above is 22 people, even if all of them held MBAs could it really be that 22 expert business administrators is too many for a global company with 350,000 employees?
Their job is to make money; they don't care, and they are not paid to care about anything else.
Now... the question is, does someone with a different background care about the company vs making money in different proportions to the set of 'expert business administrators'?
I posit that yes, someone with a different background will have different priorities to simply 'make as much money as possible right now'.
