No, because it doesn't make any sense.

In order for memcheck to work it needs to track the status of every 
individual bit of memory - as soon as code was allowed to run outside of 
memcheck changes could be made to memory that memcheck wouldn't know 
about and from then on all it's reports would be worthless.

You would get false alerts about uninitialised memory where that memory 
had in fact been initialised while memcheck was disabled and wouldn't 
get alerts about memory that, for example, was freed during that period.
