Tufts’ own faculty pages separate these into two distinct titles, rather than a single combined professorship name.

• The official Tufts Biology faculty page lists Michael Levin as "Vannevar Bush Professorship, Biology" and, on a separate line, "Distinguished Professor, The School of Arts and Sciences."
• Tufts’ official named-professorships page likewise says "Michael Levin is the Vannevar Bush Professor, Department of Biology."

So the article’s wording combines two different honors into one title. The accurate formulation is that Levin is the Vannevar Bush Professor and a Distinguished Professor at Tufts, not the "Vannevar Bush Distinguished Professor."
