If the course reversal is a regular procedure turn, no, but if it's holding pattern in lieu of procedure turn, well...the FAA never said specifically that just the entry maneuver was enough to cover the 61.57(c)(1)(ii) requirement for "Holding procedures and tasks," but they didn't say it wasn't, either. The AIM 5-4-9a5 says, "The holding pattern maneuver is completed when the aircraft is established on the inbound course after executing the appropriate entry," and I've always taken that to mean that it fills the square. However, to be 100% certain, you'd have to write to the Chief Counsel and wait four months for an answer, but I think this is one of those questions best left unasked. So, I suggest that if you do the HPILPT (even if just the reversal part), you log the approach, note "holding" in the Remarks block, and move on.
