This fixes the issue with eulernova, but not with pagellaovereuler. pagellaovereuler uses euler-with-pagella-math as a goodie file, but that is missing from the distribution. (I simply copied euler-math.lfg for my use case). 

With tweak=fixoldschool, \startcases doesn't work correctly (see attached):

\usetypescriptfile[euler]

\definetypeface[mainfont][rm][specserif][CharisSil][default]
\definetypeface[mainfont][mm][math] [eulernova][default]
\definetypeface[mainfont][tt][mono] [dejavu][default] [rscale=0.8, features=none]
\setupbodyfont[mainfont,10pt]

\starttext
\startTEXpage[offset=1mm]
  \startformula
    \startcases
      \NC A \NC B \NR
      \NC C \NC D \NR
    \stopcases
  \stopformula
\stopTEXpage
\stoptext
