VCEsat for that transistor is 90mV typ, 250mV max.
That bit's ok.
The BAT41 has a Vf of about 700mV at 10mA though.
I can't see this working.

Also remember that once driven into saturation the transistor will take a little time to come out of it. Whether that will be an issue at this frequency I don't know.
