"Tankie" in the traditional sense of someone who uncritically supports the USSR in the handling of 1956's uprising? Probably not.

While Kruschev's use of tanks in 1956 was heavy handed, the Hungarian alliance with the Axis in WWII and participation of Operation Barbarossa, lingering fascist sympathisers and nationalists remained in Hungary.

This coupled with the Communist Party of Hungary's less than equitable redistribution of land/castles/other properties earlier in the 1950's (favouring giving properties to ranking CPH members instead of distributing it to the proletariat equally). This created resentment for the Party, and an image of the Communists as no better than the Monarchy that came before or the Fascists that came after.

The Hungarian uprising had elements of fascist sympathisers, monarchists, bourgeoisie, etc but also legitimate critics of the handling of the situation. It never should have come to that, and a more educated/self critical Communist Party in Hungary could have prevented things from getting that far. The people should have benefitted a lot more from a better redistribution of wealth.

The above issues coupled with Soviet distrust of Hungarians (since they did invade the Soviet Union in the 40's) led to a swift and harsh reaction towards the uprising, seeing it as just a reactionary revolt.

Now, am I a tankie in the Reddit redefinition, of anyone that critically supports Cuba, China, Vietnam and their style of government? Yeah, I suppose I am. This is no more radical a position than Malcolm X or the Black Panthers who also supported the late USSR, China and Cuba.
