You'll need approx 19v to power and charge the laptop. Your only way would be to use an inverter but that won't be worth the hassle.
In car laptop chargers do exist.
Consider the risk of damaged laptop if you use a charger from a dubious source built with cheap cost cutting design and components.
I would go for something like this

Simple answer is yes, two options, one a 12 volt to laptop voltage, depends on laptop requirements how easy to find. And second which I have used, is a 12 volt to 230 volt AC inverter and use standard laptop power supply.
I have two, a 150 watt stand alone, and a car starting unit with a 300 watt inverter built in. Both seem to work OK.
The down side with any inverter is they draw current simply to work. Some more than others, so even with fully charged laptop switched off, it is using some power.
I tried using the 150 watt unit to charge a mobility scooter, with near fully charged batteries worked OK, but after use, found the battery charger wanted more than the inverter could deliver, so maintaining the laptop battery a 150 watt may be OK, but recharging the laptop battery it may fail.
The problem is they quote the current used at 120 volt, which is a lot higher than what is used at 230 volt, so only way to know is to measure, with a energy meter or clamp on, reading spec does not help that much.
