Is it safe to lose 40 lbs in 2 months?

Perhaps, but only if very severely obese, like around 500lb+, and under close medical supervision for deficiencies or complications.

For someone in less extreme circumstances, 0.5%-1% of current weight per week is a reasonable plan, with a bias toward the 0.5% if not under medical supervision.

For many people, 40 pounds in two months would be literally impossible.

To lose 5 pounds a week, a person would need to eat on average 2500 fewer calories than they burn per day. Many people don't burn that many calories: To lose that fast, they'd have to eat zero for 2 months, while carrying out their normal life. They could burn more via exercise, but exercise doesn't burn as many calories as many people think.

Even most who who burn over 2500 calories daily don't burn hugely more than 2500. They'd have to eat tiny amounts to lose that fast - unrealistic for most to stick with for 2 full months.

You don't give us enough info about you to give opinions whether it could be safe for YOU. Odds are against it being safe, based on what I wrote above.

No

As Ann said, you'd have to be severely obese to be SAFE about it. Anyone that uptakes that isn't obese will severely have malnutrion issues (if you don't eat you don't supply the macro/micro nutrients to sustain a healthy body) and things happen like hair falling out, women losing periods, loss of muscle mass, etc.

It’s possible when I juice (7lbs in 7 days program) I lose 2lbs a day working out 30 minutes a day. A lot of people freak out but if you are following a nutrition plan that’s been tried and tested like the one I did you can do it safely. Some people do it for 28 days so I’m guessing the lose more than 40lbs in that time. There’s such mixed messages around it I find it all very interesting. The diet industry say it’s not safe to lose more than 2lbs a week. But if you have bariatric surgery they lose way more than that and no one is screaming it’s not safe. So I honestly feel they hoodwink us and keep us in the diet trap.

All I’d say don’t do anything too drastic. Listen to your body and if you feel ill stop and get support.

More info needed. Probably no. What's your definition of "safe"? Will you die? Probably no.
