I wouldn't assume that, but I've previously tried 45 micron diamond
compound placed on an iron plate for flattening the backs of chisels and
plane blades.  I remember it working just 'OK'.  It was slow and I
eventually switched to the blue zirconia alumina belts, but to be fair
some of the blades I was working on then were in fairly rough shape.

On something like a blade bevel, I expect that size grit would work well
for initial sharpening of a newly-ground edge and probably for removing
small nicks, but I've not tried it for that.

I got mine from Tools for Working Wood.  That was probably 10 years ago
or so, though,  and I've not shopped for any diamond abrasives since
then. 

There's an older Amplex Abrasives (now owned by Saint-Gobain) catalog
here:

www.efqinc.com/pdf/AbrasivesAmplexCatalog2008-2009.pdf

that provides brief information about available grit sizes and
applications for diamond compounds.
