Probably not, but it will depend on the plan. The reason you can rollover old 401k balances is not because you're leaving a company, it's because you're no longer eligible to contribute to the company's 401k plan. Most plans make you ineligible to continue participating if you're not working there anymore. Since the plan is being transferred, you're not leaving it, and so your ability to roll it over is not triggered. You see this sometimes with corp acquisitions.
To answer this definitively you need to look at the actual plan documents. Or you can check out the IRS model plan, on which most 401k plans are based.
