Nope, can’t be. The Hebrew word that you have quoted as “arise” actually means “stand up”. It’s Michael who “stands up” to protect the 144,000 that God promised to protect those elect. Michael wasn’t “taken out of the way”, he is on duty protecting those Israelites. Besides, it’s not Michael protects the “church”. Each church has a different angel, see Revelation.
OK, provide another scripture that identifies the "he" in 2 Thessalonians 2:7.
I never suggested it was. I believe you suggest the "he" is either:
1. The Holy Spirit, or
2. The Church.
If you have any scriptural evidence outside of 2 Thessalonians regarding the identity of "he", please provide it.
