Nope, not on the combined charts because they were counted as separate SKU's... and released at a much more competitive time of year.

See here

note: it is kind of bogus that Sun/Moon are not counted together in some instances. They are literally the same game with a slight variation and people almost always (in terms of lifetime charts) combine mirror Pokemon games (Gold/Silver, Red/Blue, etc.)

You could argue some people double dip. Maybe even some more. See it this way: if the sales are counted split, Nintendo has TWO top-sellers at once.
