I am using psoc creator for development of CY8C4125LQS-S433 device , as per family data sheet
of 4100S P4.0 and P4.1 have alternate function of uart , however
when i try to map UART RX , TX pin to these pin , it throws error cannot be reached to these pins .

This is because the SCB[0] is not implemented in that PSoC 4100S devices.
The CY8C4146LQS-S433 device has three SCB blocks and the device CY8C4125LQS-S433 has two SCB blocks. The difference between these devices is if the SCB[0] block is implemented or not.
You can see the P4[0] is not listed in the drop down list because P4[0] cannot be used for UART.

UART has dedicated pins which are shown as green squares when assigning in pins view. There are only few choices depending on which SCB you choose. Try unlocking your pins and let the fitter choose a valid combination.

Can you please post your complete project or a shortened version that shows the error so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
