Yes, easily. Microtargeting and related campaigns can be distinguished entirely by the content of they present. Microtargeting is just a technique that can be used for good or bad. In the case of Obama's campaign, nobody has accused them of misleading or false information. Brexit and the the US 2016 election was almost defined by misleading or false information (as you can see by lingering Pizzagate, QAnon, and Bengazi conspiracy theories).
Amused at the downvotes. It is true. You can not like Clinton and not vote for her, or Obama. I don't judge and people can disagree. But the amount of false content in those campaigns (which came to be known as "fake news" after the fact) was unprecedent, was aided/spreaded by foreign sources, and was largely on partisan lines. Evidence includes https://news.stanford.edu/2017/01/18/stanford-study-examines... among countless others). It would be just as wrong if, say, the Sander campaign did the same thing.
