The only thing I've found mentioning row size when doing the loads relates to loads using Polybase. Then the row size needs to less than 1 MB. https://docs.microsoft.com/en-us/azure/data-factory/connector-azure-sql-data-warehouse

I concur. The correct answer is 'yes' since the no size limitation update (PolyBase) applies to only SQL Server 2019+. To date, Azure Synapse Analytics still has a cap at 1 MB.

Row size should be still maximum 1 MB. So answer is YES. Also according to latest updates https://docs.microsoft.com/en-us/sql/relational-databases/polybase/polybase-versioned-feature-summary?view=sql-server-ver15
