Why do you think that? The F6F and F4U had two-stage superchargers that gave both aircraft a service ceiling of around 37,000 feet in the F4U-1 and the F6F-5, and over 41,000 feet in the F4U-4 and F4U-5. The R2800 was more than capable of extended high altitude flight as was demonstrated by the WWII C-46 and the post war T-29/C-131 and C-118, all of which used the R2800 and regularly flew at altitudes similar to the B-17s and B-24s.
Both aircraft escorted B-17s and B-24s in the Pacific, so why would it be a stretch to believe they couldn't do the same in Europe? The only real drawback the aircraft had over the AAF fighters was range. The Corsair only had a range of around 1100 miles even with a centerline tank, while the P-51D could make well over 1600 miles. Even the later F4U-4 couldn't get more range even with it's twin drop tank capability because they removed the wing tanks.
