Well, 'Merlin's Return: Harry Potter' is another one. It's a bit different as it starts with Merlin being reborn as Harry. The author does a great job of exploring how Merlin's ancient magic would influence the modern world of Harry Potter and the challenges he would face.
One popular 'Harry is Merlin' fanfic is 'The Boy Who Lived Twice'. It weaves an interesting tale where Harry somehow gets reincarnated as Merlin in the past. The story does a great job of blending the magic systems of both universes.
There's also 'Harry Potter: Merlin's Heir'. In this fanfic, Harry discovers that he has a connection to Merlin and embarks on a journey to uncover his newfound heritage. It has some really cool action scenes and a unique take on how the two mythologies interact.
