No, there's a difference.  If you cut down the board too much, you
can't solve the local game.  You can, however, find moves that tend to
be worth considering from a global perspective, or semi-local
perspective (eg owl reading), even though you can't get definitive
answers.  If, however, you cut down the game only somewhat, you can
get correct answers (in some cases, anyway, like some endgame
positions).
