No. You can manually work your way up the stack using break ’ and .z.s to show the function, though that doesn’t always work well.
Alternatively some people have written code themselves that wraps selected functions and places the stack somewhere, though its hard to do it entirely correct and it obviously slows things down.

Subject : [personal kdb+] Call stack
The q documentation in
http://code.kx.com/wiki/JB:QforMortals/execution_control#Debugging
states
To terminate execution and empty the call stack, issue (</tt>) from the command line.
Is there a way to display the call stack (in q or in k) similar to the $si command in APL?
