Bad idea. You don't know the operating environment in that situation. The laptop could be embedded in luggage with no possibility of cooling. If the laptop wakes up and hibernation hangs (e.g. because the CPU overheats itself compressing and encrypting hibernation data), the resulting confined heat will damage the hardware until the battery gives up. Usually nothing as spectacular as a fire happens, but each incident typically wipes a few percent off the battery capacity. I once had a Macbook wipe out 80% of its battery capacity in one day doing that (Linux has no monopoly on hibernate bugs).
Back in the days of spinning rust in laptops you could break the hard drives with surprise hibernations too. Even today a hot SSD is not a happy SSD, and severe data loss can be expected.
Current laptops can sit for days in suspend state. Heck, some of them now run 24+ hours while displaying a login prompt. I hardly use suspend for anything less than international travel, and I only use hibernation for dual-booting tool when a VM won't do the job.
