It all depends how desperate you are for a job and what is your current situation. If you are unemployed/desperate to get out of current company, dont push your luck and just accept Company B since this kind of kuching kurup exec level they most likely have 3-4 other backups and will not hesitate to drop you.

If you are employed and ok with hanging around current company, can consider take risk to drag Company B and see if possible for them to wait until you finish talking to Company A, but chances quite low if you ask me.
