you can omit \language since you've already set the main language (after that 
language is used for local language switching)

for that you need a ss math font; in the simple case it could be made to work 
but since in math characters can come from any of the (about) 4 math fonts you 
would get inconsistent output. So, if you want to gamble, you may try this:

% define a typeface

\definetypeface [modern] [rm] [serif] [modern-base] [default]
\definetypeface [modern] [ss] [sans]  [modern-base] [default]
\definetypeface [modern] [tt] [mono]  [modern-base] [default]
\definetypeface [modern] [mm] [math]  [modern-base] [default]

% overloaad a mapping

% \startfontclass[modern]
%   \definefontsynonym [ComputerModernMath-Roman]  [ComputerModernSans]
%   \definefontsynonym [ComputerModernMath-Italic] [ComputerModernSans-Italic]
% \stopfontclass

\startfontclass[modern]
   \definefontsynonym [MathRoman]  [Sans]
   \definefontsynonym [MathItalic] [SansItalic]
\stopfontclass

% initialize the typeface

\setupbodyfont[modern,ss]

\starttext
Some text, we can read it without serifs. But the formula: $ \frac{1}{x-2} $
is not in the same font.
\stoptext

you can put this in one of the dark corners of the wiki -)
