Yeah should be fine, but run it through your fingers well, look for any noticable soft spots or damaged sections. As long as it was kept dry and out of direct sunlight, it's unlikely to have suffered anything other than lonlieness at not being used. It is your life line though, so make sure you are confident that it hasn't been in contact with any chemicals, oils, detergents or so on. To straighten out any kinks that have developed from it's storage, try hanging it as stretched/ flaked out as possible from a building roof or something...either unweighted or with light weights attached to pull it straight.
