Perfectly legal to do that per NEC if allowed by local inspectors,
Rod and pipe electrodes should be installed flush with or below finished grade and must be installed with at least 8 feet (2.4 m) of length in direct contact with the soil. Any exposed portion of a rod or pipe electrode and any connections above grade must be physically protected. When a vertical depth of 8 feet (2.4 m) is not possible, rod and pipe electrodes are permitted to be driven at an angle of 45 degrees or less from vertical, or buried in a horizontal trench 30 inches (76 cm) or more below grade.
Rod and pipe electrodes are required to be at least 8 feet (2.4 m) in length and should be free from non-conductive coatings. Rod and pipe electrodes must be installed below the permanent moisture level, or water table, 30 inches (76 cm) or more below finished grade when installed in a horizontal trench. Rod and pipe electrodes must be spaced at least 6 feet (1.8 m) apart.
A single rod or pipe electrode with a measured ground resistance of more than 25 ohms must be supplemented by one additional grounding electrode, although no additional ground resistance testing is required by the NEC.
