How long are you thinking of storing this laminate and in what kind of environment? Unheated but dry storage unit or shed would be fine but if it’s a damp place where the laminate will just keep absorbing moisture, I’m gonna say no.
Humidity is the greater concern. I don't believe where you live outside of direct sunlight laminate would suffer JUST from excessive heat. I'm less certain about freezing conditions-----again it's cold + wet that worries me, and mostly the wet.
Put a dehumidifier in there if you can. I had a leaky van once that I would run an extension cord to and ran a dehumidifier in there during the rainy season. Kept my tools from rusting as well as it kept the van from getting moldy.
