Sure, there's some overlap.
The Tea Party movement was all about reducing taxes, smaller government and reducing the debt.
The Trump movement is all about anti-PC, silenced majority, nationalism, etc.
The Tea Party was more about "get the government out of my life" whereas the Trump movement is more about "the government should be doing more for me".
Further evidence:
"RAND tested several queries to clearly divide Trumps support from his rivals. For example, they found that Trump crushes Ted Cruz among voters who both strongly believe that immigrants threaten American customs and values" and among voters who "strongly favor" raising taxes on the richest American households. But voters who agreed with the statement people like me don't have any say about what the government does were 86.5 percent more likely to prefer Trump. This feeling of powerlessness and voicelessness was a much better predictor of Trump support than age, race, college attainment, income, attitudes towards Muslims, illegal immigrants, or Hispanic identity."
