No, it isn't!
Casting any object pointer to (and from) void* or char* is guaranteed to work, while float to integer incurs in the undefined behaviour curse.

for (int i=0; i<4; i++)
buf[i] = ((char*)&my_float)[i];
for (int i=0; i<4; i++)
buf[i] = ((char*)(int32_t*)&my_float)[i];
On the other side, this would incur UB:
int32_t my_int = *((int32_t*)&my_float);
