Yes.
Again the The US lost 40 generals in WW2.
If the Generals are on the battle field like there Russian Generals seem to be, of course they can die like any other soldiers.
Generals don't have Superman powers. They are not immune to bullets or bombs.
Russia has 200k troops committed. They have lost 4 generals to combat in 3 weeks. It’s an annualized rate of 69 generals a year so the number of generals they are losing for the size of their force is newsworthy.
The WW2 comparison is to a period of just under 4 years and a much larger force. Of the 40 generals that died during the war, only 11 were the result of combat while four were killed in plane crashes, two were executed by the Japanese, and one was killed by friendly fire. There were also more generals, since larger force. Those losses are not as newsworthy.
