you forgot the 'default' so you basically force basemode which is does 
permanent features .. add/subtract works only in node mode

\definefontfeature
   [f:onum]
   [onum=yes,pnum=yes]

\definefontfamily [test] [serif] [AntykwaTorunska] 
[features={default,f:onum}]
\definefontfamily [test] [sans]  [Myriad Pro]
\definefontfamily [test] [mono]  [DejaVu Sans Mono]
\definefontfamily [test] [math]  [Xits Math]

\setupbodyfont[test,12pt]

\starttext
     test 1 2 3 test 1/2 \subtractfeature[f:onum] test 1 2 3 test 1/2
\stoptext
