ConTeXt doesn’t use the same style switches as LaTeX.

1. sf is not a valid argument for the second argument of \definefontfamily

2. You need a real math font for mathematics, a text font doesn’t work 
because it lacks many parameter for math mode.

3. You can use the font fallback mechanism to replace certain character 
in the math font with characters from a text font.

\definefontfamily     [mathfont] [rm] [Tex Gyre Bonum]
\definefallbackfamily [mathfont] [mm] [Tex Gyre Adventor] 
[preset=math:lowercaseitalic]
\definefallbackfamily [mathfont] [mm] [Tex Gyre Adventor] 
[tf=style:italic,range=0x068,offset=0x0210E]% Planck constant
\definefontfamily     [mathfont] [mm] [Tex Gyre Pagella Math]

\setupbodyfont[mathfont,10pt]

\starttext

Normal text.

\math{a + b = c}

\stoptext
