Usually you can, but it better be worth it. You’ll have to get an officer to say they’re willing to accept the risk with a high level legal counsel.
If you tossed this idea up to that level, you’d piss the officer off for wasting his time and burn the relationship with the lawyer.
Also, this team was pretty infamous at that point for not playing nice with the corporate structure (eg naming the OS Plan 9). Sure, they were rockstars to nerds, but Unix, etc. never made Bell/AT&T real money. Wasn’t their fault, but they never got internal clout and were just a small, weird group in a giant company.
My current role is the first where I've extensively worked with counsel. My biggest misconception going into these discussions was that it'd be a transactional, approval-gated thing: I make a request, they kick it around, then come back and say "yes" or "no" and that would be the end of it.
What I've found is exactly what you describe: if I come to legal asking for a "no" – which I've done more than a handful of times – that's an easy answer that comes out of an email. But when I come wanting their approval, if I can get past the first meeting with counsel the next one is with officers, you are pitching the benefits while the lawyers are talking about risks, and if you can convince everyone to take the risks you get what you want. Just be sure to write down meeting minutes and send them around; no one at that level was taking notes ;)
"We want to distribute a ton of IP with unclear/insufficient releases" has almost no benefit and a mountain of risk for any company. It's no wonder the lawyers said no.
