I agree that “discerning the body” also has that wider application, as discerning the need for social communion with one another as well as a spiritual communion with God. For that reason, as well as for the reasons of sacramental theology the Catholic Communion is closed to those who in their own spiritual home do not enjoy a valid Sacrament of the Eucharist; and it is open to those who do, like the Orthodox.
We do participate in wider social activities, such as ecumentical prayers, gatherings, festivals and so on. We are encouraged to visit other houses of worship and participate in things that do not contradict the Catholic faith, such as scripture readings.
However, the passage in 1 Cor 11 that is our view also has the narrow Eucharistic focus, because in it St. Paul directly mentions the literal and not metaphorical body of Christ delivered up for us. If he meant solely the discernment of the body of Christ which is the Church, he would not have referred to His passion. Neither in John 6 it is possible to substitute the Church for the flesh of Christ which is “food indeed”.
