Just checked the Lenovo PSREF for my MIL-STD-810H certified Zen3+ Thinkpad:
Operating Environment
Temperature[1]
Operating: 5°C (41°F) to 35°C (95°F)
Storage and transportation in original shipping package: -20°C (-4°F ) to 60°C (140°F)
Storage without package: 5°C (41°F) to 43°C (109°F)
Humidity
Operating: 8% to 95% at wet-bulb temperature 23°C (73°F)
Storage and transportation: 5% to 95% at wet-bulb temperature 27°C (81°F)
Altitude
Maximum altitude (without pressurization): 3048 m (10,000 ft)
Notes:
1. When you charge the battery, its temperature must be no lower than 10°C (50°F).
So if you're in a really hot climate that might not be enough. Rn it's 31°C here in the shadows and idling SoC temperature is ~45°C.
In that case, just go for a rugged laptop ala Getac. The S410 is specified for -30° to 65°C (-20 to 145 °F) operating ambient temperature. Whether you are is on a different spec sheet...
