If you can position the mount so you can attach to two studs, it will be fine.
If you can position the mount so you can attach to one stud, and use toggle bolts to attach the four corner holes of the mount, that will be fine too.
If you had only drywall to attach to, with toggles or other heavy duty supports, you might still be OK. I couldn't assure it because it really depends on the condition of the drywall, framing, etc. But for example these anchors
are rated for over 100kg pounds shear strength in 1/2" drywall. I'd use a bunch to be safe - I'd arrange them in a "W" pattern
And as I said, no guarantee, but I personally would be confident with this mount if the wall is well constructed and in good condition.
