No. That is illegal.

Step 1: You need to find an employer who can process your H1B.
Step 2: The new employer should file your H1B with COS (if you want to join the new employer immediately upon the H1b approval)
Step 3: If the the H1b gets approved by USCIS, then you can work for the employer (starting the effective "Valid From" date on the new I-94).

Change of status (COS) to H1B may take anywhere between 2 - 3 months. There is a premium process available for an additional $1000 which will take only 15 days.

You don't need to inform your current employer about this. They won't know unless you tell them. However, keep in mind that you can work for the new H1B employer only if your H1B is approved with COS (new I-94). Otherwise you need to get the visa stamped and re-enter in H1B visa to work for that employer.
