I am unsure if you can check in at T4 and then take the shuttle bus to T2. Apparently some claim that this is possible - but I personally have not tried it. Note that T4's arrival / departures are segregated - the arrivals has a dedicated transfer area. Going from departures, you apparently need to "negotiate with the security guy manning the transit area" - and it is not clear where this is
What I have done is check in at T4, then take the landside shuttle bus to T2, and cleared immigration etc at T2. Again, some others have reported failures clearing customs etc at a non-T4 terminal. So it really is YMMV.
Unfortunately T4 in SIN seems to be in its own little world...
