Instead of suppressing the warning, given that LilyPond adds an invisible
"auxiliary" stem to the whole notes, for creating the tremolo beam,
I think it should be better to explicitly set the stems on both notes,
according to the beam's position:
%%%
\version "2.22.0"
upper = { s1 }
lower = {
\clef treble
\override Beam.positions = #'(10 . 11)
\repeat tremolo 8 { \stemUp c''''16 \change Staff = "upper" \stemDown
c''''16 }
}
\score {
<<
\new Staff = "upper" \upper
\new Staff = "lower" \lower
>>
}
%%%
