I have not researched that specifically, but the team at BuzzSumo analyzed 120 million articles and found a similar result. They found the optimal length for an article on Facebook to be 2000-2500 words and on LinkedIn to be 3500-4000.
So what you suggest could be true, the length of an article that does well on Facebook is shorter than LinkedIn and I'd argue that an article on Facebook is likely for a more casual reader than on LinkedIn.
However, even 2000 words is a fairly long article. They also found that articles under 500 words perform the worst.
