If you could drop Mount Everest (height: 8848 m) to the bottom of an ocean trench, would its summit reach the level of the ocean's abyssal plains?

No, the Abyssal Plain is 4500 m down. Mount Everest is 8850 m (rounded). The ocean trench is 11,000 m down. Subtract 11,000m from 8850m, and you get 2150m. This means that its less than the abyssal plain so it doesn't reach anywhere near the abyssal plain.
