Bathroom Fitting

Running soil pipe from under-stair WC & through kitchen out to the back

I'm looking at putting a WC under the stairs in a standard 3-bed terrace (main bathroom upstairs at the back). The kitchen is downstairs to the back, looking over the back garden, and the main bathroom soil pipe drops down the back accordingly. The question is, would it be possible to run a soil pipe from a macerator on a new WC under the stairs, and take the pipe behind the kickboard in the kitchen (under the kitchen cabinets) and knock through the back wall of the kitchen to meet the main soil pipe out the back? Or will building regs not allow a soil pipe to run above floor-level through a kitchen like this? Any better solutions you might suggest? Thanks!
