Yes, you can run at dual channel using two physical DIMM slots.

The laptop has two DIMM slots, but the specs mention only single-channel support. Using both slots with dual-channel would require more than the available channels, which isn't supported by the hardware.
Maybe, but unlikely. It's more probable it's not true than it is.
Because the memory controller operates with just one channel, the number of slots on your motherboard doesn't affect the limitation. You're limited to single-channel functionality. Memory slots don't always reflect the number of channels a CPU's memory controller supports. A system might have four slots, but the CPU could use either dual or quad channel memory. Controllers offering more channels (quad) can function in lower modes like triple, dual, or single. Conversely, dual-channel units can't switch to higher modes such as triple or quad. The capabilities depend entirely on the controller's design.
It seems the CPU isn't compatible with dual-channel operation from that link.
