Immediately toss the hot pasta in a large bowl with the butter to coat. While tossing the linguine, gradually sprinkle the cheese, pepper, and enough of the reserved cooking liquid evenly over the linguine to moisten. Add the arugula and toss to combine. Season the pasta, to taste, with salt. Divide the pasta among 6 plates and serve.
