In Qt yes, others like gtk2 no.
I've created and edit with button inside and it works (qt).
This should work:
EditBitBtn := TBitBtn.Create(Self{TMyEdit})
EditBitBtn.Height := Height - 4;
EditBitBtn.Width := 32; {eg TMyEdit width is 100}
EditBitBtn.Align := alRight;
EditBitBtn.Parent := Self;
EditBitBtn.Visible := True;
Only thing you should check in ComponentState or ControlStyle (cannot 
remember now), that maybe you should add to TMyEdit (in constructor) 
that it allows child controls ...
