It looks to me that the outer tire diameter is the controlling dimension for tire fit with the Vado fenders. Tires rated in inches (28x2, etc) are generally interpreted to mean approx outer diameter x tire width. So a 28x1.75 tire may have approx the same outer diameter as a 28x2 tire, the 28x2 being wider. The Vado standard tires are 47-622 which are approx 28x1.75. As such, a 28x2 tire may fit. A lot depends on the tread design and how close the manufacturer holds the tire to a true 28 inch outer diameter. IMO it's iffy at best.
I personally would have more confidence that a 50-622 tire could be found that would fit as the applicable Euro standards are more specific as to what these figures actually mean (width x inner diameter). The tread design would need to be a similar low profile design as the spec does not address outer diameter. Seems like it's still a risk for a 3mm gain in width.
There's a good discussion of this at https://www.schwalbetires.com/tech_info/size_markings. . This site also offers a full listing of all common tire sizes with equivalents in inches and French sizes (700x45c, etc).
