No it cannot.
Not directly, but with a bit of work, maybe.
I found this interesting information from wikipedia:

In the mid-20th century, kerosene or tractor vaporising oil (TVO) was used as a cheap fuel for tractors. The engine would start on gasoline, then switch over to kerosene once the engine warmed up. A heat valve on the manifold would route the exhaust gases around the intake pipe, heating the kerosene to the point where it was vaporized and could be ignited by an electric spark.
In Europe following the Second World War, automobiles were modified similarly to run on kerosene rather than gasoline, which they would have to import and pay heavy taxes on. Besides additional piping and the switch between fuels, the head gasket was replaced by a much thicker one to diminish the compression ratio (making the engine less powerful and less efficient, but able to run on kerosene). The necessary equipment was sold under the trademark "Econom".[32]
During the fuel crisis of the 1970s, Saab-Valmet developed and series-produced the Saab 99 Petro that ran on kerosene, turpentine or gasoline. The project, codenamed "Project Lapponia", was headed by Simo Vuorio, and towards the end of the 1970s, a working prototype was produced based on the Saab 99 GL. The car was designed to run on two fuels. Gasoline was used for cold starts and when extra power was needed, but normally it ran on kerosene or turpentine. The idea was that the gasoline could be made from peat using the Fischer–Tropsch process. Between 1980 and 1984, 3,756 Saab 99 Petros and 2,385 Talbot Horizons (a version of the Chrysler Horizon that integrated many Saab components) were made. One reason to manufacture kerosene-fueled cars was that in Finland kerosene was less heavily taxed than gasoline.[33]
Kerosene is used to fuel smaller-horsepower outboard motors built by Yamaha Motors, Suzuki Marine, and Tohatsu. Primarily used on small fishing craft, these are dual-fuel engines that start on gasoline and then transition to kerosene once the engine reaches optimum operating temperature. Multiple fuel Evinrude and Mercury Racing engines also burn kerosene, as well as jet fuel.[34]
