Without a tube, not a chance.
Tube or no tube, doesn't make a difference.
The tube doesn't add to a tire's structure, which comes entirely from the cloth plies. If the plies are intact, or only very slightly damaged, the tire is still going to be sound until/unless the fabric starts to fray or pull apart.
The reality is that any tire can be cut by a piece of glass and blow out at any time, so the added risk of riding an OK but not perfect tire isn't that high.
So, IMO, this tire is fine, but like any tire needs to be watched for signs that the end is near. Those usually take the form of lumps, bulges and twist, often felt as thumping. Feel or hear the thump, thump, thump, it's time to stop and inspect, then possibly limp home at reduced speed.
