The answer is yes, it is allowed. If it is an uncontrolled field (no tower) you will be cleared for the approach and be advised that runway x is closed. If there is a tower they will of course clear you to land on the open runway. We use the same operation all of the time at airports with one approach when the wind favors the other direction. But I will add I have seen ATC's not issue legal clearances when they should have because they were not standard or the norm. We have our share of people who only do the minimum and have no interest in really learning all of the rules.
